Question

4 The given figure represents a pentagon ABCDE in which sides AB and ED a
parallel to each other and ZB: LC:ZD=7:3:8. Find ZB, ZC and ZD.
(Hint: AB|| ED, -LA + ZE=180°)​

Answer 1

Answer:

A pentagon ABCDE with sides AB and ED parallel to each other.

Then, AE behaves as a transversal.

∠BAE+∠AED=180

o

(Sum of interior angles of the same side of transversal is supplementary)

So,∠A+∠E=180
