Question

Find the value of A​

Answer 1

Answer:

1) 180-60=120

2)180-157=28

2)180-92=88

3)180-125=55

Answer 2

Solution:

Two angles are called supplementary when their measures add up to 180 degrees.

1.
60 + A = 180
A = 180 - 60 = 120

2.
157 + A = 180
A = 180 - 157 = 23

3.
92 + A = 180
A = 180 - 92 = 88

4.
A + 128 = 180
A = 180 - 128 = 52
