Answer 1

Answer:

x=15

Step-by-step explanation:

well by angles in parallel lines

angle 1 is equal angle 2

so we have

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

Answer 2

Answer:

15

Step-by-step 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
