To find the complementary angles, we can set up the equation 3x + 2x - 5 = 90. Simplifying the equation, we get 5x - 5 = 90. Adding 5 to both sides, we have 5x = 95. Dividing both sides by 5, we get x = 19. Therefore, the angle measures are 3(19) = 57 and 2(19) - 5 = 33.
The correct answer is B. 33 and 57.
