Question

M< 9 = 6x and m< 11 = 120. Find the value of x so that line c is parallel to line d

A. 20
B. 30
C. 114
D. 15

Answer 1

x = 20

Explanation:

m<9 and m<11 are alternate angles (so that the line c is parallel to line d)

Therefore their measure is equal to each other

if m<9 is represented with 6x:

6x = 120 divide both sides by 6

x = 20
