In ΔPQR, the measure of ∠R=90°, the measure of ∠Q=22°, and PQ = 9.2 feet. Find the length of RP to the nearest tenth of a foot.

Answer 1

3.4

Explanation:

\text{SOH-CAH-TOA}

SOH-CAH-TOA

\sin Q = \frac{\text{opposite}}{\text{hypotenuse}}=\frac{x}{9.2}

sinQ=

hypotenuse

opposite

​

=

9.2

x

​

\sin 22=\frac{x}{9.2}

sin22=

9.2

x

​

9.2\sin 22=x

9.2sin22=x

Cross multiply.
