The answer is D, the alternate exterior angles theorem.
Alternate, because the two angles are on opposite sides of line t.
Exterior, because both angles are outside of the parallel lines.
Therefore, alternate exterior angles theorem.

Answer:
374 I think 15 x 22 = 330 + 44 =374
Step-by-step explanation:
I think 15 x 22 = 330 + 44 =374
-2y = 48 + 6x
-6x - 2y = 48 ——(1)
-6x + 9y = -84
-6x = -84 -9y ——(2)
Substitute (2) into (1):
(-84 -9y) -2y = 48
-84 -9y -2y = 48
-84 -11y = 48
-11y = 48 + 84
-11y = 132
y = - 12
Substitute y = -12 into (1):
-6x -2(-12) = 48
-6x + 24 = 48
-6x = 48 -24
-6x = 24
X = -4
ANS : y= -12, x= -4
