Question

What are the values of m and n

Answer 1

• m = 20°, n = 45°

Explanation:

Both of the triangles are isosceles as marked on the diagram.

The right triangle has missing angles of:

• n = 90°/2 = 45°

The missing angles of the bigger triangle:

• m + n = 1/2(180° - 50°)
• m + 45° = 65°
• m = 20°
