Question

Find the value of x and y. Identify the type of angle pair!!

Answer 1

40y+20=60y-40

60y-40y=20+40

20y=60

y=60÷20

y=3

8x=2x+30

8x-2x=40

6x=30

x=30÷6

x=5

(40×3+20) = 140

8×5 = 40

(2×5+30)=40

(60×3-40)=140

Answer 2

y = 3

x = 5

Explanation:

40y + 20 = 60 y - 40 because opposite angles are equal

solve this equation

40y + 60 = 60 y

60 = 20 y

3 = y

8x = 2x +30

6x = 30

x = 5
