The triangle is an isosceles triangle so that means the base angles must be congruent.

The sum of the interior angles of a triangle add up to 180 degrees.

Subtract 52 degrees from 180 degrees.

180 - 52 = 128

Divide 128 degrees by 2.

128/2 = 64

m∠X = 64°

Hi!

The triangle pictured is an isosceles triangle. Isosceles triangles all have two sides of the same length and a third side, with the angles opposite the sides of the same lengths called the base angles. The base angles have the same measure, and it's only the third angle that has a different one.

In this case, the base angles are X and Z, because they are opposite the sides that are the same length in the triangle. Therefore, angle X has the same measure of angle Z.

A triangle's angles always add up to 180 degrees. Therefore, you know that m∠Y + m∠X + m∠Z = 180. And since you know m∠Y is 52 degrees, then you can say:

52 + m∠X + m∠Z = 180

And since m∠X is equal to m∠Z:

52 + m∠X + m∠X = 180

m∠X * 2 = 180 - 52

m∠X * 2 = 128

Divide everything by 2:

m∠X = 64 degrees

Anvisha [2.4K]
For a question like this, all you have to do is remember that a percentage is simply a fraction expressed as a decimal. So, all we have to do is:
\frac{187}{550}, and then multiply our decimal answer by 100 to get the percentage:
\frac{187}{550} = 0.34
0.34 x 100 = 34
Therefore 34% of the students walk to school.
I hope this helped and remember to please try and understand the maths that got the answer, not just writing the answer down :))

amm1812

Answer: 70

Step-by-step explanation:

a^2 + b^2 = c^2

24^2 + b^2 = 74^2

576 + b^2 = 5,476

-576             -576

b^2             =4,900

(square root)

Use the interactive number line to help complete each exercise. Place points at -1 and -4. Complete the inequality: -1 -4. Place
Sliva [168]

Question might not be complete

Answer and explanation:

The signs -1 and -4 lie on the negative side of the number line, left of zero(positive right of zero).

The opposites for each number would be +1 and +4 which would all be on the right side of zero on the number line

Inequality signs or statements to represent greater and lesser number on the number line using the numbers above as examples would be:

-1<+1

-4<-1

+1>-1

+1<4

-1-4<1+4

Numbers that don't have signs attached to them are automatically positive numbers
