Answer:
A. The third angle in a triangle where the other two angles measure 33° and 57°
Explanation:
You want to know the sort of math problem that might be solved using the equation ...
A. Triangle
You know the sum of angles in a triangle is 180°, so if two of them are 33° and 57°, the unknown angle x in a triangle can be found using Paisley's equation.
B. Hypotenuse
If Paisley is trying to find the hypotenuse of a right triangle with legs 33 and 57, we expect to see the equation ...
33² +57² = x²
C. Bowling
The average is obtained by dividing the total of scores by the number of scores. The score required for an average of 180 could be found using the equation ...
(33 +57 +x)/3 = 180
This is not Paisley's equation.
D. Third side
The area of a triangle is related to the side lengths by Heron's formula. It can also be found using a couple of trig formulas. In either event, the relation is very much different from the one Paisley wrote.

Additional comment
Paisley's equation gives x=90, indicating her triangle is a right triangle.
If 33 and 57 are side lengths of a triangle with an area of 180 square units, the third side is about 25.40752 units long. This value is not obtained using Paisley's equation.
For an average of 180, the bowling score would need to be 450, a score that is not possible in one game.
