Answer:

1. angle A = 119 degrees

2. angle B = 56 degrees

Step-by-step explanation:

To solve for angle A:

7x - 21 = 6x - 1

x - 21 = -1

x = 20

7(20) - 21 = 119 degrees

To solve for angle B:

2x + 18 + 6x + 8 = 90

8x + 26 = 90

8x = 64

x = 8

6(8) + 8 = 56 degrees
The answer to A is 119 and the answer to B is 56
