The two angles are complementary, which means they add up to 90 degrees.
So, we have the equation:
3x + (2x - 5) = 90
Combining like terms:
3x + 2x - 5 = 90
5x - 5 = 90
5x = 95
x = 19
Therefore, the two angles are:
3x = 3(19) = 57 degrees
2x - 5 = 2(19) - 5 = 38 - 5 = 33 degrees
Therefore, the correct answer is:
C. 33 degrees and 57 degrees
