Question

Solve for x,y, and all the missing angles

Answer 1

a = 90

b = 40

c = 60

d = 30

x = 18

y = 14

Explanation:

90 + d + c = 180

90 + 2y + 2 + 3y + 18 = 180

5y + 110 = 180

5y = 70

y = 14

d)

2y + 2

2(14) + 2

30

c)

3y + 18

3(14) + 18

60

a)

a + 90 = 180

a = 90

b)

a + b + 50 = 180

90 + 2x + 4 + 50 = 180

2x + 144 = 180

2x = 36

x = 18

2x + 4

2(18) + 4

40
