Question

Pqrs is a trapezium in which pq||sr. if angle p=55 degree and angle q=70 degree find angle r and angle s

Answer 1

angle p + angle s = 180 ( co- interior )
55 + angle s = 180
angle s = 180-55
angle s =125


also, angle q + angle r = 180 ( co interior )
70+ angle r = 180
angle r = 180-70
angle r =110
