Question

pqrs is a trapezium with PQ parallel to SR if Angle B equal to 30 degree angle Q equal to 50 degree find angle r

and angle s

Answer 1

In the given trapezium pqrs,
< p = 30°
<p = < s
but angle p = 30 °
so. angle s = 30° ....( opposite angles are congruent )
Similarly,
angle q = 50°
angle q = angle r
but angle q = 50°
so. angle r = 50° ..... ( opposite angles are congruent )
