Answer 1

Answer:19

Step-by-step explanation:if you look at angle 148 it is the same as the one you are figuring out. Just solve it and you will get 19.

Answer 2

Answer:

x = 19

Step-by-step explanation:

148 and 7x+15 are alternate interior angles and alternate interior angles are equal when the lines are parallel

148 = 7x+15

Subtract 15 from each side

148-15 = 7x+15-15

133 =7x

Divide each side by 7

133/7 =7x/7

19=x
