Question

. If ∠A and ∠B are two adjacent angles of a parallelogram. If ∠A = 70°, then ∠B = ? ​

Answer 1

Answer:

110° =b

Step-by-step explanation:

as as the sum of adjacent angles of a parallelogram are 180 degree then we need to subtract 70 degree from 180 degree to get the measure of angle b and hence the measure of angle b is 110 degree
