Question

a and b are ajacent angles of a parallelogram. if a = 70⁰ then b= ?​

Answer 1

Answer:

sum of adjacent angle=180

a+b=180

70+b=180

b=180-70

b=110degree

HOPE THIS HELPS!

Answer 2

Answer:

a + b = 180° ..... ( Adjacent anglesof parallelogram are supplementary)

70 + b = 180

b = 180 - 70
