Question

Determine the Value of x for the diagram shown.

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

Answer 1

X = 60
180 - 120 = 60 so that gives you the angle next to 120 then since it’s an isosceles triangle the next 2 angles are going to be the same because of the 2 dash’s so you do 180 - 60 = 120
120 divided by 2 equals 60
