Quantity A is greater.
Quantity B is greater.
The two quantities are equal.
The relationship cannot be determined from the information given.
We know that two angles on the same line must add to 180 degrees.
So, we can write: (2t + 12) + (t² - 2t + 24) = 180
Simplify: t² + 36 = 180
Keep going: t² = 144
So, EITHER t = 12 OR t = -12
HOWEVER, if t = -12, then the angle on the left = 2(-12) + 12 = -12
Since we can't have negative angles on the GRE, we know that t cannot equal -12
This mean it MUST be the case that t = 12
We get:
Quantity A: 12
Quantity B: 12
Answer: C
