Answer 2

The angles in the triangles are the same, so you know the triangles are similar. Sides PQ and AB correspond as do sides PR and AC. Because the triangles are similar, you know that
  PR/AC = PQ/AB
  PR/24 = 5/20
Multiplying this equation by 24 gives
  PR = 24*(5/20) = 6

The appropriate choice is ...
  C. 6
