Answer:
x = 18. y = 54
Explanation:
first we we figure out the degrees of the spot where N is.
(I know N references the line but ill be using it to call the spot)
72 + N = 90
subtract 72 from both sides
N = 18
So since opposite angles are the same
2x + N = 3x
2x + 18 = 3x
subtract 2x from both sides
18 = 1x
divide by 1 both sides
18 = x
______
now we add all the angles from the left sides to make 180
2x + N + 72 + y = 180
we know x is equal to 18 and N is also 18
2(18) + 18 + 72 + y = 180
simplify
36 + 18 + 72 + y = 180
add
126 + y = 180
subtract both sides by 126
y = 54
