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:
x = 20
Step-by-step 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
