Answer:
Both A and B
Step-by-step explanation:
sum of opposite interior angles is equal to the exterior angle.
That line that is made out of angles 1 and 2 is straight. What we know about straight lines is that they're 180°. This means that ∠1 and ∠2 are supplementary, adding up to 180°.
∠1 + ∠2 = 180
∠1 = (x + 81)
∠2 = (2x)
(x + 81) + 2x = 180
3x + 81 = 180
3x = 99
x = 33
The answer is x = 33.
The correct answer is C. 5/8
