Answer 1

the answer of your question is in the attachment....

thanks...

Answer 2

hey!!!

In triangle APB
P-40°
A-180-100(Supplementary angle)
A-80°
Sum of all sides of a triangle -180°
So A+P+B=180°
80+40+B=180
120+B=180
180-120=B
B=60°


In angle ABC
B=180-60
=120°

Alternate angles of a trapezium add up to 180°
angle BCD=180-120=60°
Y=60°
X=40+60+x=180(sum of triangle PDC)
x=100+x=180
x=180-100
x=80°


X=80°
Y=60°

Hope it helps you
