Answer 2

Answer:

a=75, b=120, c=75 and d=120

Step-by-step explanation:

a=75 degree( vert. opp. angles are equal)

b=120 degree(vert. opp. angles are equal)

let an angle inside trapezium be x

x+120=180(sum of adj. angles on a str. line =180)

or, x=180-120

=60

d+60=180(int. angles are supplementary)

So, d=180-60

or, d=120 degree

c=75 degree(alt. angles are equal)
