Answer:
∠TVX = 49°
x = 52°
x = 57.5°
BC = 6 cm
Step-by-step explanation:
Question 1
Angle at the Centre Theorem:
∠UTV = 1/2 ∠UOV = 134 ÷ 2 = 67°
Angles around a point add up to 360°
⇒ interior angle of ∠UOV = 360 - 134 = 226°
The sum of interior angles of a non-cyclic quadrilateral is 360°
⇒ ∠OVT = 360 - 26 - 226 - 67 = 41°
As WVX is a tangent, it forms a right angle with the radius (OV)
⇒ ∠TVX = 90 - 41 = 49°
Question 2
Angles on a straight line add up to 180°
The angle between a tangent and a chord is equal to the angle in the alternate segment.
Therefore ∠x = 180 - 68 - 60 = 52°
Question 3
As CD is a tangent ⇒ OC = radius ⇒ ∠OCD = 90°
The sum of interior angles of a triangle is 180°
⇒ ∠COD = 180 - 90 - 25 = 65°
As ∠COD =∠AOB then ∠AOB = 65°
As OB and OA are radii, triangle AOB is an isosceles triangle. Therefore ∠OBA = ∠OAB
Therefore x = (180 - 65) ÷ 2 = 57.5°
Question 4
As BC is the tangent to the smaller circle, OA is perpendicular to BC.
Therefore, triangle OAB is a right triangle with hypotenuse 5 cm.
Using Pythagoras' Theorem a² + b² = c² (where a and b are the legs, and c is the hypotenuse of a right triangle):
⇒ AB² + 4² = 5²
⇒ AB = √(5² - 4²) = 3
⇒ BC = 2 x AB = 3 x 2 = 6 cm

“The sum of 5 times a number and 8 is 9.”
Answer:
Hello lovely person! Welcome to Brainly! <3
Your answer will be 5x + 8 = 9
Step-by-step explanation:
We know that the word sum indicates addition, and this applies to the number 5. So we know that we will be adding 5 somewhere in this equation.We are also given the phrase "times a number." Times means multiply. When we are given an unknown variable ("a number") we use a letter to represent it, such as X.Now we know that the word "is" means equals, so that is where we put the = sign. Since it says "is 9" we know that it means "= 9"So we can put all of this information together to create our equation.If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers. Have an amazing day.

Write an equation of the line that passes through (2,5) and is parallel to the line 2y = 3x + 10.
Answer:
y = 3/2x - 8 hope I helped
Step-by-step explanation:
To find the equation of a line, we need a point and a slope. We're given a point, and we can easily get the slope. First let's solve 2y = 3x + 10 for y so we can get the slope (recall that y = mx + b is the slope-intercept form, and m is your slope).
2y = 3x + 10 --> almost there already, just divide everything by 2 to get y by itself.
y = 3/2x + 5 --> now you have it in the y=mx + b form, so your slope is 3/2
They asked for the parallel line, remember parallel lines have the same slope, therefore you use the same slope.
Now we know that our slope is m = 3/2 and our point is (2, -5)
You can always find the equation of a line using the Point-Slope Formula:
y - y1 = m(x - x1) --> our x1 is 2 and our y1 is -5, and slope is 3/2
y - (-5) = 3/2(x - 2) --> Be careful when you have minus a negative number, like we do here. It becomes:
y + 5 = 3/2(x - 2) --> now distribute the 3/2
y + 5 = 3/2x - 6/2
y + 5 = 3/2x - 3 --> now we can subtract 5 from both sides to get it into slope intercept form.
y = 3/2x - 8 --> This is the equation of a line that is parallel to 2y=3x+10 & passes through (2, -5)
Find the indicated probability. A spinner has equal regions numbered 1 through 15. What is the probability that the spinner will stop on an even number or a multiple of 3?.

Marques is a waiter at a restaurant. Each day he works, Marques will make a guaranteed wage of $25, however the additional amount that Marques earns from tips depends on the number of tables he waits on that day. From past experience, Marques noticed that he will get about $14 in tips for each table he waits on. How much would Marques expect to earn in a day on which he waits on 17 tables? How much would Marques expect to make in a day when waiting on tt tables?
The amount he will get on that day = the guaranteed wage + the amount of table he waits x 14
So, Marques expect to make 25 + 14 x 17 = 25 + 238 = $263
A game of "Doubles-Doubles" is played with two dice. Whenever a player rolls two dice and both die show the same number, the roll counts as a double. If a player rolls doubles, the player earns 5 points and gets another roll. If the player rolls doubles again, the player earns 5 more points. Whenever the player rolls the dice and does not roll a double, they lose points. How many points should the player lose for not rolling doubles in order to make this a fair game? Three-fifths 1 5 Three-fifths.
Using the expected value of a discrete distribution, it is found that the amount of points the player should lose for not rolling doubles in order to make this a fair game is of 1.
What is the expected value of a discrete distribution?The expected value of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.
In this problem, considering 6 out of 6^2 = 36 outcomes are doubles, we have that the distribution is:
P(X = 5) = 1/6.
P(X = x) = 5/6.
A fair game means that the expected value is of 0, hence:
[tex]5\frac{1}{6} - \frac{5x}{6} = 0[/tex]
[tex]\frac{5x}{6} = \frac{5}{6}[/tex]
[tex]x = 1[/tex]
The amount of points the player should lose for not rolling doubles in order to make this a fair game is of 1.

Find the unknown sizes of angles
Answer:
R=50 b=130 a=135
Step-by-step explanation:
Sum of Internal angles = 180
R= 180-85-45 = 50
missing interior angle R = 50
If a side of a triangle is produced, then the exterior angle that is formed is equal to the sum of the two interior opposite angles.
P+Q = 85+45= 130 b=130
P+R = 85+50 = 135 a=135
To solve this problem, we would have to add the sum of angles in a triangle and then find the missing side. Furthermore, value of R, a and b are 50°, 135° and 130° respectively.
Data;
P = 85°Q = 45°a = ?b = ?Sum of Angles in a TriangleThe sum of angles in a triangle is equal to 180° and we can find the missing side on R.
[tex]P+Q+R = 180^0\\85^0+45^0+R = 180^0\\130^0+R=180^0\\R = 180 - 130 \\R = 50^0[/tex]
Since we know the value of R and Q, we can proceed to find a and b.
[tex]Q+ a = 180\\[/tex]
The reason behind this is that the sum of angles on a straight line is equal to 180^0
[tex]45+a = 180 \\a = 180 - 45 \\a = 135^0[/tex]
Now let's find the value of b
[tex]R + b = 180\\R = 50^0\\50 + b = 180\\b = 180 - 50 \\b = 130[/tex]
From the calcuations above, the value of R, a and b are 50°, 135° and 130° respectively.

Step-by-step explanation:
Since the triangles are similar to eachother, they will have the same ratio.
One way to solve is dividing 8 by 2. Since 12 divided by 2 is 6,
we can expect 8 divided by 2 to be the missing side we are looking for.

A4 ore
Explanation:
There are 8 letters in the word "GEOMETRY".
Use the nPr permutation formula with n = 8 and r = 7 and you'll find that 8P7 = 40320.
Or you can compute it like this 8*7*6*5*4*3*2 = 40320

Given the polynomial 2x3 18x2 − 18x − 162, what is the value of the constant 'k' in the factored form? 2x3 18x2 − 18x − 162 = 2(x k)(x − k)(x 9) 3 6 9 18.
The value of the constant 'k' in the factored form factorization the provided polynomial equation is 3.
What is polynomial equation?Polynomial equations is the expression in which the highest power of the unknown variable is n (n is real number).
The factor of a polynomial is the terms in linear or equation form, which are when multiplied together, give the original polynomial equation as result.
The given polynomial equation in the problem is,
[tex]2x^3 +18x^2 - 18x - 162[/tex]
The factor of the polynomial equation are given as,
[tex]2(x+ k)(x - k)(x +9)[/tex]
First find out the factors to compare and find the value of k.The above equation has the unknown variable x and the highest power of this unknown variable is 3.
Take out the highest common factor 2, which can divide each term of the above equation (2, 18, -18, -162). Thus,
[tex]2(x+ k)(x - k)(x +9)=2(x^3 +9x^2 - 9x - 81)[/tex]
Take out the highest common factor to make the groups as,
[tex]2(x+ k)(x - k)(x +9)=2(x^2( x+9) - 9(x + 9))\\2(x+ k)(x - k)(x +9)=2( x+9) (x^2 - 9)\\2(x+ k)(x - k)(x +9)=2( x+9) (x^2 - 3^2)[/tex]
Use the property of difference of the square for the (x²-3²) term as,
[tex]2(x+ k)(x - k)(x +9)=2( x+9) (x+3)(x-3)\\2(x+ k)(x - k)(x +9)=2 (x+3)(x-3)( x+9)[/tex]
On comparing the two equation, we get the value of k as 3. Thus, the value of the constant 'k' in the factored form factorization the provided polynomial equation is 3.
