Question

hey mate my next question from you plzz solve it thanx good night sd tc

Answer 1

As we know opposite angles of cyclic quadrilateral sum is 180

So 4y + 20 - 4x = 180

Also 3y - 5 -7x + 5 = 180
3y - 7x = 180
4y - 4x = 160

y - x= 40

3y - 3x = 120
3y - 7x = 180

subtract

4x = -60

x= -15

y = 40 + x = 25

So angles are 70, 60, 120,110
