Question

In parallelogram EFGH, m∠1 = 3x – 5, m∠2 = x + 10, and m∠3 = 2x + 15. What is m∠4?

Answer 1

Answer:

.

Step-by-step explanation:

The opposite angles are equal in a parallelogram.

Therefore,

9x-14° = 7x+8°

2x = 22°

x = 11°

thus the angle H = 99-14° = 85°

And Angle G = 180° - angle H

Since the sum of adjacent angles is 180°

Angle G = 180-85 = 95°
