Question

Find the value of x and y.

Answer 1

Opposite sides are equal.

2x+3y=12       ...... (1)

Angles are equal.

30x+11y=112  ...... (2)

Solve equations (1) and (2).

15(1)-(2):

   30x+45y=180

-  30x+11y=112

--------------------------------------

          34y = 68

                y = 2

2x+3(2)=12

2x=6

x = 3
