Question

Determine the value of x for the diagram shown.

A) 30
B) 45
Eliminate
C) 60
D) 80

Answer 1

Hello there,

In order to solve this equation we look at the relationship between the two triangles.

A straight line is equal to 180° so...

• 180 - 120 = 60°

Since the triangle on the left has two sides that are equal that means the angle measure is also equal for those two sides.

Therefore, x would be equal to 60° and the correct answer would be C.

Hope I helped,
