Answer:

Consecutive interior angles are supplementary, so:

100 + 7x - 4 = 180

7x + 96 = 180

7x = 84

x = 12

Answer:

x = 12

Step-by-step explanation:

If g and h are parallel , then

(7x - 4)° and 100° are same- side interior angles and sum to 180°

sum the angles, equate to 180 and solve for x

7x - 4 + 100 = 180 ( simplify left side )

7x + 96 = 180 ( subtract 96 from both sides )

7x = 84 ( divide both sides by 7 )

x = 12

For g and h to be parallel , then x = 12
