PQRS is a trapezium with PQ || SR. If ∠P = 300 and ∠Q = 500, find ∠R and ∠S |
|
Answer» Q||SR,and PS is transversal then ∠P+∠S=180°(sum of CONSECUTIVE interior ANGLES on the same of transversal is 180°)30°+∠S=180°∠S=180°-30°∠S=150°Since PQ||SR, and QR is transversal then ∠Q+∠R=180°(sum of consecutive interior angles on the same of transversal is 180°)50°+∠R=180°∠R=180°-50°∠R=130° |
