Final answer:
To make angles 2 and 4 parallel, x should be -35
Step-by-step explanation:
To find the value of x that would make angles 2 and 4 parallel, we need to set the two angles equal to each other.
2x + 10 = 4x + 80
Subtract 2x from both sides:
10 = 2x + 80
Subtract 80 from both sides:
-70 = 2x
Divide both sides by 2:
x = -35
Therefore, the value of x that would make angles 2 and 4 parallel is -35.
