Question

Given cyclic trapezium ABCD in 1 point
which AD || BC and B = 60°,
Determine angle A.​

Answer 1

Answer:

A=120°

Step-by-step explanation:

Because ,

AD || DC , The sum of angle between parallel lines is 180°

So ,

B=60°

A and B are angles between parallel lines so there sum will be 180°

So,

A + B = 180°

A + 60° = 180°

A = 180° - 60°

A = 120°
