Question

find the mesure of angle x in the figure below​

Answer 1

Answer:

x = 60°

Step-by-step explanation:

Given,

the two sides of the triangle are equal.

Therefore, it is an isosceles triangle and it's base angles are equal.

That means, the supplementary angle to 120° is equal to x.

Therefore, x + 120 = 180

x = 180 - 120 = 60°
