Answer 2

Answer:

ABCD is a cyclic Quadrilateral

Therefore, sum of opposite angles is 180°

A + C = 180

2x + 4 + 4y - 4 = 180

2x + 4y = 180

x + 2y = 90

x = 90 - 2y

B + D = 180

x + 10 + 5y + 5 = 180

x + 5y + 15 = 180

x + 5y = 165

90 - 2y + 5y = 165

90 + 3y = 165

30 + y = 55

y = 55 - 30

y = 25

x = 90 - 2(25)

x = 90 - 50

x = 40

x + y = 40 + 25

x + y = 65
