Question

in the following figure, a pair of parallel lines are cut by a transversal. find the measure of each lettered angle​

Answer 1

140°+Angle 1 =180° (Same side of Transversal)

Angle 1 = 180°-140°

Angle 1= 40°

Angle 3 = 120° (Vertically Opposite Angle)

Angle 2 + Angle 3 = 180°

Angle 2 + 120° = 180°

Angle 2 = 180°-120°

Angle 2 = 60°
