Question

Find the measure of the indicated angle in each triangleThe choices are A=180B=156C=103D=360

Answer 1

∠ VUX = 156°

Explanation:

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

∠ VUX is an exterior angle of the triangle , then

∠ VUX = 53° + 103° = 156°

Answer 2

In this problem, we have that

53+103=x -----> by Exterior Angle Theorem (The exterior angle is equal to the sum of the two non-adjacent interior opposite angles)

In this problem

mmso

x=156 degrees

therefore

m
