Question

angle A and B are 2 adjacent angles of a parallelogram if angle A is 60 then angle B is ?​

Answer 1

angle B is 120°

Step-by-step explanation:

if A &B are adjacent angles of a parallelogram that means they are supplementary angle

therefore the sum of supplementary angke is 180°

hence m angle A +m angle B=180

60+ B=180

m angle B=180-60=120°
