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
