Question

In the figure below, line l is parallel to line m, PQ = QR and angle RQS = 80 degree. What is the measure of angle PQR? Pls answer fast, i will mark brainliest

Answer 1

Angle PRQ = RQS = 80° (inter.alt.angles ) since RQ is transversal

angle RQS = RPQ ( PQ=QR)

In triangle PQR,

angle P = angle R and angle P+Q+R = 180°(angle sum property)

angle Q = 180°-(P+R)

= 180°- (80+80)°

= 180°-160°

= 20°
