It is a right triangle, so all angles add to 180 degrees. Thus, we find: a) $B = 180 - 90 - 67 = 23^{\circ}$ b) Angle RPC corresponds to angle A in the other triangle. Since the triangles are similar, they have the same measure. The, $RPC = 67^{\circ}$ c) We use a proportion: $\frac{AC}{5} = \frac{26}{13} \\ AC = 10$ d) We use a proportion: $\frac{CB}{12} = \frac{26}{13} \\ CB = 24$
