Answer:

B

Step-by-step explanation:

If the 2 lines were parallel, then

5x - 10 = 70 ( alternate angles )

Add 10 to both sides

5x = 80 ( divide both sides by 5 )

x = 16

For the 2 lines to be parallel then x = 16

Answer:

B.16

Step-by-step explanation:

First I would Make an equation:

For example set (5x-10)=70

Add 10 to both sides:

5x-10+10=70+10

Simplify:

5x=80

Divide both sides by 5:

5x/5=80/5

simplify:

x=16

In conclusion the answer is B.16
