Question

please solve question no 4

Answer 1

1) 5x + 2x + 2x = 180° (Angle Sum Property)

9x = 180°

x = 180°/9

x = 20°

Therefore, value of each angle:

5x = 5*20° = 100°

2x = 2*20° = 40°

2x = 2*20° = 40°

2) 3x + 2x + x = 180° (Angle Sum Property)

6x = 180°

x = 180°/6

x = 30°

Therefore value of each angle:

3x = 3*30° = 90°

2x = 2*30° = 60°

x = 30°

Hope it helps :)
