Answer:

option 3

Explanation:

The right vertex of the triangle is vertically opposite 60° and is congruent

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

117° is an exterior angle of the triangle , then

x + 60 = 117 ( subtract 60 from both sides )

x = 57
