Question

Find the values of x and y.

A. x = 73.3, y = 15.3
B. x = 73.3, y = 20.7
C. x = 100, y = 10
D. x = 100, y = 26

Answer 1

C, (x = 100, y = 10)

Explanation:

hi again,

(2x - 70) = (x + 30), by the Alternate Exterior Angles

x - 70 = 30

x = 100

(2x - 70) + 5y = 180, by the Linear Pair Theorem

2(100) - 70 + 5y = 180

200 - 70 + 5y = 180

130 + 5y = 180

5y = 50

y = 10
