Question

in a quadrilateral ABCD , AB||DC. If A:D=2:3 and B:D=7:8 , find the measure of each angle​

Answer 1

Step-by-step explanation:

given ,

AB||DC

let angle A and D be 2x and 3x

then ,

A + D = 180 ( AB || CD )

2x + 3x = 180

5x = 180

x = 36

Therefore ,

A = 2 × 36

= 72

B = 3×36

= 108

again , let B AND C be 7x and 8x

then,

B + C = 180

7x + 8x = 180

15x = 180

x = 12

therefore ,

B = 7×12

= 84

C = 8×12

= 96
