A=(2x + 10)
C=(y-50)
we know that sum of opposite angles of cyclic quad. is 180.
So, angle A + angle C =180
thus, 2x + 10 + y - 50 =180
2x + y - 40 = 180
2x + y = 180 + 40
2x + y = 220 .......................(1)
Similarly, angle B + angle D = 180
x + 20 + y - 10 = 180
x + y + 10 = 180
x + y = 180 - 10
x + y = 170......................(2)
Then, subtract eq(2) from (1)
2x + y = 220
x + y = 170
- - -
x = 50
Put the value of x in equation (2)
50 + y = 170
y = 170 - 50
y = 120
Hence, x = 50, y = 120
