Question

Activating Schema: Draw the figure described below. Then solve for length PR. Right Triangle PQR with the following characteristics: PQ is perpendicular to PR, QR = 47 mm, and Angle Q = 52°

Answer 1

The given triangle is

To solve for PR, we have to use the sine function which is equivalent to the ratio between the opposite leg and the hypothenuse.

$\begin{gathered} \sin 52=\frac{PR}{47} \\ PR=47\cdot\sin 52 \\ PR\approx37.04 \end{gathered}$

Hence, PR is 37.04 mm long, approximately.
