Question

Answer it with the process of geometry: angles.
1. If x and 54 form a linear pair, find x.
2. If 2x and 2x are adjacent angles in a linear pair, find them.

Answer 1

Step-by-step explanation:

1)

×+54= 180° ( linear pair)

x= 180-54

x= 126°

2)

2x+2x=180° (linear pair)

4x= 180°

x= 45°

Each adjacent angle= 2x= 2×45°= 90°
