Answer 1

15

Explanation:

Since angles 1 and 2 are known as "alternate interior angles", they are equal to each other.

Since they are equal, we can set the equations equal to each other as well.

7x = 5x + 30

-5x -5x

2x = 30

x = 15

Answer 2

x=15

Explanation:

well by angles in parallel lines

angle 1 is equal angle 2

so we have

`7x=5x+30\\\\7x-5x=30\\\\2x=30\\\\x=15`
