Question

Pls help in class 9 lines and angles

Answer 1

Given PQ || RS

Angle PAB = Angle ABC ( alternate angle )

( alternate angle )= 70°

Angel ABC + Angle BAC = 100° ( angle sum property )

70°+ Angle BAC = 100°

Angle BAC = 100°-70° = 30°

Angle PAB + Angle BAC + Angle CAQ = 180° ( sum of angle of straight line )

70° + 30° + Angle CAQ = 180°

Angle CAQ = 180° - 70° - 30°

Angle CAQ = 180°-100° = 80°
