Step-by-step explanation:
I assume the figure is the one attached below.
One pair of similar triangle is ΔRSP and ΔRPQ.
We know this because ∠R = ∠R, and ∠S = ∠P (both are right angles). Therefore, by AA similarity, the triangles must be similar.
Using the similarity statement, we can write and solve a proportion:
RS / RP = RP / RQ
4 / RP = RP / 16
64 = RP²
RP = 8
