Question

Two isosceles triangles are shown below. If 180 - z = 2y and y = 69, what is the value of x ?

Answer 1

Answer:

x = 69

Step-by-step explanation:

Knowns:

y = 69

180 - z = 2y

180 - z = 2 (69)

180 - z = 138

-z = -42

z = 42

Since there is no picture, I am guessing x is the third angle.

x = 180 - (y + z)

x = 180 - (69 + 42)

x = 180 - 111

x = 69
