Find the value of x that makes m||n
.
135°
m
(2x + 15)
n

Answer:
x = 60
Step-by-step explanation:
Since m is parallel to n, that means they are equal to each other.
In other words:
135 = 2x + 15
Solve for the variable:
120 = 2x
60 = x
Check your work:
135 = 2(60) + 15
135 = 120 + 15
135 = 135
Correct!
Answer:
x = 60
Step-by-step explanation:
For these two lines to be parallel, the angles m and n must be equal. Thus, 135 = 2x + 15.
Excellent. Let’s solve this equation. Subtract 15 from each side. 120 = 2x. Divide by 2, and we get 60 = x, so x = 60.
Hope this helps!
