Question

8. In a quadrilateral ABCD, it is being given that AB || DC.
a: d = 2:3 and B: C = 4:5.
Find the measure of each angle of quadrilateral ABCD.
[Hint : 2х + 3x = 180 and 4у + 5y = 180.]​

Answer 1

Answer:

A=72,B=80,C=100,D=108

Step-by-step explanation:

a:d=2x+3x=180

5x=180

x=180/5

x=36

a=72,d=108

B:C=4y+5y=180

9y=180

y=180/9

y=20

B=80,C=100
