Question

Using the markings below, determine which of the following is the measure of angle 2

Answer 1

• 4. 132°

Explanation:

Both the triangles on the left and right are isosceles

The top angle of the triangle on the left:

• 180° - 2*69° = 42°

The top angle of the triangle on the right:

• 90° - 42° = 48°

This is the same angle as supplementary with angle 2:

• ∠2 = 180° - 48° = 132°

Correct choice is 4
