The diagram shows a isosceles right triangle, follow the steps to explore relationships between Saint triangles, measure the length of each leg and hypotenuse
The length of the sides are given by the 45°–45°–90° triangle theorem.
Correct responses:
AB = 1
AC = 1
BC = √2
How to find the length of an Isosceles Triangle?The 45°–45°–90° triangle theorem is one that states that the ratio of the lengths of the sides of triangles having interior angles of 45°, 45°, 90° is expressed as 1 : 1 : √2
We know that the lengths of the legs of an isosceles triangle are equal. Now, the legs of the given isosceles right triangle in the attached file are AB and AC.
Thus, we can say that, AB = AC
If the length of AB s 1 unit, then we have;
AB = AC = 1
Using Pythagoras theorem, we have;
BC² = AB² + AC²
Which gives; BC = √2
Therefore, by plugging in the length of AB = AC = 1, we have;
AB = 1
AC = 1
BC = √2 ≈ 1.414
The above values are in the ratio 1 : 1 : √2, which now corresponds with the 45°-45°-90° triangle theorem.

Which of these events is not mutually exclusive?
A) the chance that you will get a heads or tails when you flip a coin once.
B) the chance that you will only study for the test alone or with a friend.
C) the chance that you will meet your friends for pizza or at a chinese restaurant for dinner today at 6.
D) the chance that you will answer the ringing phone or take a walk.
The chance that you will get a heads or tails when you flip a coin once (option A) is not mutually exclusive.
Mutually exclusive events are events that cannot occur at the same time, or that do not have any overlap. In the case of flipping a coin, the possibility of getting a head and the possibility of getting tails are independent of each other, and both can occur simultaneously. Therefore, the chance that you will get heads or tails when you flip a coin once is not mutually exclusive.
On the other hand, the other events listed (B, C, and D) are mutually exclusive. The chance that you will only study for the test alone or with a friend cannot occur simultaneously, as you can either study alone or with a friend, but not both. Similarly, the chance that you will meet your friends for pizza or at a Chinese restaurant for dinner today at 6 cannot occur at the same time, as you can either go to the pizza place or the Chinese restaurant, but not both. And the chance that you will answer the ringing phone or take a walk cannot occur simultaneously, as you can either answer the phone or take a walk, but not both.

The chance that you will get a heads or tails when you flip a coin once (option A) is not mutually exclusive.
this question is related to probability.
mutually exclusive
Mutually exclusive events are those events that do not occur at the same time.
For example, when a coin is tossed then the result will be either head or tail, but we cannot get both the results. Such events are also called disjoint events since they do not happen simultaneously.
probability
Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.

A clock tower is 15 feet tall. How long is its shadow when the sun is at an altitude (angle above the horizon) of 60 degrees? Give your answer in feet.
The length of the shadow when the sun altitude is 60 degrees is 8.7 feet.
How to find the side of a right triangle?The clock tower is 15 feet tall. The length of the shadow when the sun is at an altitude of 60 degrees can be calculated as follows:
This situation forms a right angle triangle.
Hence, using trigonometric ratios,
tan 60 = opposite / adjacent
where
opposite side = 15 feet
adjacent side = x
tan 60 = 15 / x
cross multiply
x tan 60° = 15
divide both sides by tan 60
x = 15 / tan 60
x = 15 / 1.73205080757
x = 8.65800865801
x = 8.7 feet
Therefore,
length of shadow = 8.7 feet.

an open tank is 3 M long 2 m wide and 1 m 50 cm deep how much amount of paint is required to paint its inside and outside if 1 kg of paint covers 20 Sq m
First, calculate the surface area of the inside of the tank by multiplying the length, width, and height: 3 m * 2 m * 1.5 m = 9 m^2.
Then, calculate the surface area of the outside of the tank by adding the surface area of all 6 sides: 2 * (3 m * 1.5 m + 2 m * 1.5 m + 3 m * 2 m) = 24 m^2.
Finally, add the surface area of the inside and outside to get the total surface area: 9 m^2 + 24 m^2 = 33 m^2.
To find the amount of paint required, divide the total surface area by the coverage per kg of paint: 33 m^2 / 20 m^2/kg = 1.65 kg.

what is unitary method ?Using the unitary approach, an issue can be resolved by first figuring out the value of a single unit, then multiplying that value by the number of units needed to solve the problem. The unitary technique is sometimes useful for multiplying and dividing by fractions because it makes sense immediately and can be done mentally if the numbers add up. This makes it a good method for defending or explaining frequently employed written fractional algorithms, like division by a fraction. The unitary technique has a formula that involves finding the value of a single unit, multiplying it by the quantity of units, and then finding the desired value.

The expression of the probability that the flight did not arrive on time at El Centro is as follows:
Fraction = 1/5Decimal = 0.2Percentage = 20%.What is the probability?Probability is the chance or likelihood that an expected outcome occurs or does not occur.
Probability describes an occurrence's relative value (ratio) over many possible events.
When the likelihood is 100% certain or uncertain, the probability is 1 or 0, respectively. Otherwise, probability as a fractional value lies between zero and one.
Air Travel
Airport: El Centro (CA) Baltimore (MD)
Arrivals (Percent on-time) 80% 82%
Did not arrive on time:
Percentage = 20% (100 - 80) 18% (100 - 82)
Fraction = 1/5 (20/100) 9/50 (18/100)

What is the measure of∠A in the triangle shown?
Answer:
23
Step-by-step explanation:
Answer:
m∠A = 70°
Step-by-step explanation:
The dashes on line segments AB and AC mean that they are equal in length. Therefore, the triangle is an isosceles triangle. This means that the two base angles, ∠B and ∠C are congruent.
Interior angles of a triangle sum to 180°. Therefore:
⇒ m∠A + m∠B + m∠C = 180°
⇒ m∠A + 55° + 55° = 180°
⇒ m∠A + 110° = 180°
⇒ m∠A + 110° - 110° = 180° - 110°
⇒ m∠A = 70°

How do you change 5/8 to an equivalent fraction with a denominator of 100
We can multiply both the numerator and denominator by 12.5 to get the equivalent fraction:
5/8 = 62.5/100
How to find the equivalent fraction?We want to rewrite 5/8 as an equivalent fraction with a denominator of 100.
Remember that if we multiply both the numerator and denominator of a fraction by the same number, then we will get an equivalent fraction.
So if that number is x, we can write:
5/8 = (5*x)/(8*x)
First, we want a denominator of 100, then the value of x must be such that:
8*x = 100
x = 100/8
x = 12.5
Then the equivalent fraction is:
(5*12.5/8*12.5) = 62.5/100

No, because (6,4) is on the line.
Step-by-step explanation:
Inequality given is y > -1/2x + 7
Point given is (6, 4)
Substitute the x coordinate and y coordinate into the equation
4 > -1/2(6) + 7
4 > -3 + 7
4 > 4
(Statement is False, hence inequality does noit hold)
First part of the answer is No
Since both the left and right side of the inequality is the same at 4, the point (6,4) lies on the line.
Hence, second part is because (6, 4) is on the line.
