Question

Abcd is a cyclic trapezium with ab || bc . if ∠a = 105° , then other three angles are

Answer 1

Let assume ABCD Is Trapezium,
where AB||CD
Angle A=105

Let's start
Angle A +Angle B=180(AB||CD AC is Trasversal,,and Angle in same side of transversal is 180°)

Here we get Angle B=75°
Similarly Angle C=105°
Angle D=75°

Hope it's Help You!!
