Answer:
x = 120
y = 21
Explanation:
Since j and k are parallel, the sum of x and 60 would be 180 because they are supplementary:
x + 60 = 180 subtract 60 from both sides
x = 120
The measure of x and (4y+36) is equal because they are alternate angles since the horizontal lines are also stated as parallel:
we know x = 120 so
120 = 4y + 36 subtract 36 from both sides
84 = 4y divide both sides by 4
21 = y
