Question

# These triangles are congruent. If is

- 45°
- 55°
- 80°
- 100°

Hint:

### In the given question, we have to find C which belongs to both the triangles so we can chose any of the triangle for the calculation. For , is given and to find , it is given that the two triangles are congruent so . Now as we have two angles of the triangle we can easily find the third side by the theorem the sum of three sides of the triangle is 180.

## The correct answer is: 80°
