Answer:

4. 132°

Step-by-step 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
