Question

The diagram shows a triangle on top of trapezium. Find the angles marked with letters in the diagram given below:​

Answer 1

Answer:

a=b=c=d=54

Step-by-step explanation:

Since,DE is a straight line

Therefore,

AED=180-126

c=54

IN ∆AED,

A+E+D=180

D=180-(72+54)

=180-126

d=54

Since BCDE is a trapezium,

BC is parallel to ED.

B=E=54

c=54

D=C=54

d=54
