Answer:

x = 70° ; y = 67°

Step-by-step explanation:

1) The triangle given in the picture is an isosceles triangle. So, the base angles will be equal to each other. (People do get confused and assume that x is a base angle. But in the figure , the triangle is rotated anticlockwise. So x is not a base angle).

Using angle sum property of triangles,

[tex]x+55+55=180[/tex]

[tex]=> x + 110 = 180\\[/tex]

[tex]=>x = 180-110=70[/tex]

2) Both the lines are parallel to each other and there's a transversal intersecting both the lines at 2 specific points. So ,

y = 67° (∵ Alternative Interior Angles are equal to each other when two lines are parallel and there's a transversal intersecting them)

Answer:

[tex]*+24x+9 = 16x^2 + 24x + 9[/tex]

Step-by-step explanation:

Given

[tex]* + 24x + 9[/tex]

Required

Fill in the gap

[tex]* + 24x + 9[/tex]

Express 24x as a sum of equal halves

[tex]* + 12x + 12x + 9[/tex]

Group into two

[tex](* + 12x) + (12x + 9)[/tex]

Factorize 12x + 9

[tex](* + 12x) + 3(4x + 3)[/tex]

Ignore the incomplete part and focus on (4x + 3)

Since the binomial is a square, then the factors of the binomial are :

(4x + 3) and (4x + 3)

So, we have:

[tex](* + 12x) + 3(4x + 3) = (4x + 3)(4x + 3)[/tex]

Expand

[tex](* + 12x) + 3(4x + 3) = 16x^2 + 12x + 12x + 9[/tex]

[tex](* + 12x) + 3(4x + 3) = 16x^2 + 24x + 9[/tex]

Hence:

[tex]*+24x+9 = 16x^2 + 24x + 9[/tex]

361-176=185

Step-by-step explanation:

Answer:

-185

Step-by-step explanation:

176-(-185)= 361

two negatives equal a positive.

so the negative becomes a positive, the "-(-" becomes "+"

so new equation is 176+185= 361

Answer:A. slope: 7, y-intercept: 10

Step-by-step explanation:

Transform the equation into slope intercept form, y=7x+10. In the form y=mx+b, m = slope and b = y-intercept

Step-by-step explanation:

m < CAD = 180 - ( 40 + 57 ) = 83

Answer:

∠C = 70°

Step-by-step explanation:

When dealing with similar triangles, the angles of both triangles are equal. With that being said, the letters of those angles typically corralete as well. In this case, we have ΔABC and ΔDEF. Based on the way those letters are arranged, we can assume the following:

∠A = ∠D

∠B = ∠E

∠C = ∠F

The question tells us ∠A = 36°. Since we know that ∠A is equal to ∠D, we know that ∠D also equals 36°. The question also tells us ∠E = 74°. Once again, since we know that ∠E is equal to ∠B, we know that ∠B is 74° as well.

Now we use that information to solve for ∠C. The sum of the angles of a triangle always adds up to 180°. Because we know that, we can solve easily:

180 - (36 + 74) = 70

∴ ∠C = 70°

Answer:

[tex]b=24[/tex]

Step-by-step explanation:

[tex]\frac{1}{2}b-16=-4[/tex]

First, start by adding [tex]16[/tex] to both sides of the equation:

[tex]\frac{1}{2} b=12[/tex]

To make this problem easier, it would be a good idea to identify [tex]0.5[/tex] as the decimal equivalent of the fraction [tex]\frac{1}{2}[/tex]:

[tex]0.5b=12[/tex]

Divide both sides of the equation by the coefficient of [tex]b[/tex], which is [tex]0.5[/tex].

(**Tip: Dividing by a half is the same as multiplying by [tex]2[/tex]):

[tex]b=24[/tex]

-

To check our work and solution, substitute the solved value of [tex]b[/tex], ([tex]24[/tex]), into the initial equation:

[tex]\frac{1}{2}b-16=-4[/tex]

[tex]\frac{1}{2}(24)-16=-4[/tex]

[tex]12-16=-4[/tex]

[tex]-4=-4[/tex]

Since both sides of the equation are equal, our solution is correct!

Answer:

b = 24

Step-by-step explanation:

[tex]\sf \dfrac{1}{2}b-16=-4[/tex]

Add 16 to both sides.

[tex]\sf \dfrac{1}{2}b=-4+16\\\\ \sf \dfrac{1}{2}b=12[/tex]

Multiply both sides by 2.

[tex]\sf2* \dfrac{1}{2}b=12*2\\\\1b=24[/tex]

Divide both sides by 1.

[tex]\sf b = \dfrac{24}{1} \\\\b =24[/tex]

Answer:

[tex]\mathbf{- 20 \pi + \dfrac{40}{3}}[/tex]

Step-by-step explanation:

Given that:

[tex]\int\limits_c {F} \, dr[/tex]

where;

[tex]F(x,y) = \langle\sqrt{x} + 10y^3+10y^2 + \sqrt{y} \rangle[/tex] and C consist of the arc of the curve, This shows that C is a closed curve.

Thus, using Green's theorem for clockwise orientation.

[tex]\int \limits_CF. dr = \iint_D \Biggl \langle \dfrac{\partial Q}{\partial X} - \dfrac{\partial P }{\partial Y} \Biggl \rangle dA[/tex]

Then;

[tex]F(P,Q) = \langle\sqrt{x} + 10y^3+10y^2 + \sqrt{y} \rangle[/tex]

[tex]\int \limits _CF. dr = -\iint_D \Biggl \langle \dfrac{\partial}{\partial} ( 10x^2 + \sqrt{y} -\dfrac{\partial}{\partial y } ( \sqrt{x} + 10y^3) \Biggl \rangle dA[/tex]

[tex]\int \limits _CF. dr = -\iint_D \Biggl \langle 10(2x)-10(3y^2) \Biggl \rangle dA[/tex]

[tex]\int \limits _CF. dr = \iint_D \Big \langle -20x+30y^2 \Big \rangle dA[/tex]

y → 0 to sin (x)        x → 0 to π

[tex]\int \limits _CF. dr = \int \limits ^{\pi}_{0} \int \limits ^{sin \ x }_{0} \Big \langle -20x+30y^2 \Big \rangle dydx[/tex]

[tex]\int \limits _CF. dr = \int \limits ^{\pi}_{0} \Biggl [ -20xy + \dfrac{30 \ y^3}{3} \Biggl ] ^{sin\ x}_{0} \ dx[/tex]

[tex]\int \limits _CF. dr = \int \limits ^{\pi}_{0} \Big [ -20x \ sin x + 10 \ sin^3x \Big ] \ dx[/tex]

replace [tex]sin^3 x = \dfrac{3}{4} \ sin x - \dfrac{1}{4} \ sin (3x)[/tex]

[tex]= \int \limits ^{\pi}_{0} -20 x sin x dx + \int \limits ^{\pi}_{0} 10(\dfrac{3}{4} sin x - \dfrac{1}{4} sin (3x) ) \ dx[/tex]

By applying integration by posits

[tex]\int (u)(v') \ dx = (u)(v) - \int (u') (v) \ dx \\ \\ u = -20x \ \ \ \ \ \ \ v'= sin \ x \\ \\ u' = -20 \ \ \ \ \ \ \ v = - cos \ x[/tex]

[tex]= (-20x) (-cos x) - \int (-20)(-cos x) \ dx + 10 \Big [\dfrac{3}{4} \ cos x + \dfrac{1}{12}\ cos (3x) \Big ][/tex]

[tex]= 20x \ cos x - 20 \ sin x- \dfrac{15}{2} \ cos \ x + \dfrac{5}{6} \ cos (3x) \Biggl |^{\pi}_{0}[/tex]

[tex]= ( -20 \pi -0 +\dfrac{15}{2}-\dfrac{5}{6}) - (0-0-\dfrac{15}{2}+\dfrac{5}{6})[/tex]

[tex]= - 20 \pi + \dfrac{15}{2}-\dfrac{5}{6}+\dfrac{15}{2}-\dfrac{5}{6}[/tex]

[tex]\mathbf{= - 20 \pi + \dfrac{40}{3}}[/tex]

Answer:

x = 3/2 or 1.5

Step-by-step explanation:

distribute 3 to the 2x and -1 by multiplying

6x - 3 = 6

add 3 to both sides to get 6x by itself and it keeps both sides equal

6x = 9

divide by 6

x = 9/6 = 3/2

x = 3/2

Answer:

{1,3,4,5,6,7}

Step-by-step explanation:

Here , U represents the universal set

L’ = {2,4,6}

L’ is what we have in the universal set but not present in set L

(m n L’)

This is the set that contains the elements that are present in both set ONLY

So this is;

{2}

(M n L’)’ = {1,3,4,5,6,7}

N’ = {1,7}

So the union of both would be;

The missing side length of the right triangle is 20.51.

"Trigonometric Ratios are defined as the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled triangle. The ratios of sides of a right-angled triangle with respect to any of its acute angles are known as the trigonometric ratios of that particular angle.

The basic trigonometric ratios are sin, cos, and tan, namely sine, cosine, and tangent ratios. The other important trig ratios, cosec, sec, and cot, can be derived using the sin, cos, and tan respectively."

Given,

Perpendicular of the triangle is 15

Hypotenuse of triangle is x

And the adjacent angle will be 180°-133° = 47°

Now, [tex]sin(47 degree) = Perpendicular/hypotenuse = 15/x[/tex]

[tex]x = 15/0.731 = 20.51[/tex]

In the to get to the answer we use sine of the triangle.

Because sin is the ratio of the perpendicular to the hypotenuse.

Hence, The missing side of the right triangle is 20.51.

Step-by-step explanation:

Answer:

c??

Step-by-step explanation:

The coordinates of B are (1,2).

A midpoint is a point lying between two points and is in the middle of the line joining the two points.

Given that, Point C (3, 4) is the midpoint of AB If the coordinates of A are (7, 6),

Formula of midpoint coordinates = (x1+y1)/2, (x2+y2)/2

Therefore, (7+x)/2, (6+y)/2 = (3,4)

Comparing both side, we get,

(7+x)/2 = 3

x = 1

And, (6+y)/2 = 4

y = 2

Hence, The coordinates of B are (1,2).
