I know what Y is but I don't know X

Mathematics
1 answer:
sertanlavr [38]2 years ago
6 0

Answer: y = 120 degrees, x = 31 degrees

Step-by-step explanation:

Y is 120 degrees because same-side exterior angles are supplementary.

Therefore, 60+ y = 180; y = 120

Since "y" and "4x-64" are supplementary, they add up to 180.

We already know y as 120.

So 120 + 4x - 64 = 180

4x = 124

x = 31

An isosceles triangle has a perimeter of 36 inches. Its base is 2
astra-53 [7]

The lengths of the sides of the triangle are 8, 8, 20

Explanation:

Given that the perimeter of an isosceles triangle is 36 inches.

The base of the triangle is 2\frac{1}{2} times longer than each of its legs.

We need to determine the lengths of the sides of the triangle.

<u>Lengths of the sides:</u>

Let x denote the lengths of the sides of the triangle.

The base of the triangle is given by

2\frac{1}{2}x=\frac{5}{2}x=2.5x

Perimeter of the isosceles triangle = Sum of the three sides of the triangle.

Thus, we have,

36=x+x+2.5x

36=4.5x

8=x

Thus, the length of the sides of the isosceles triangle is 8 inches.

Base of the triangle = 2.5(8)=20 \ inches

Hence, the three sides of the isosceles triangle are 8, 8, 20
