Question

If ∠A and ∠B are two adjacent angles of a parallelogram. If ∠A = 110°, then ∠B = ?

Answer 1

Answer:

angle b= 110

because angle a and angle b are opposite angles of the parallelogram.

Answer 2

Answer:

angle B= 70 degree

Step-by-step explanation:

sum of two adjacent angles =180 degree

angle A + angle B = 180

110 + angle B = 180

angle B = 180 - 110

so, angle B = 70 degree . answer
