Question

Find the measure of A as indicates in the picture.

In case the picture blurs

Top angle = x + 63

Left angle = x + 96

Right angle = x + 149

Answer 1

∠A = 58°

Explanation:

all triangles contain 180°

180° - 149° = 31°

x + 63° + x + 96° + 31° = 180°

combine like terms:

2x + 190° = 180°

2x = -10°

x = -5°

∠A = -5° + 63° = 58°
