Question

find pr.write your answer as an integer or as a decimal rounded to the nearest tenth.pr =

Explanation:

Step1: Identify trigonometric ratio

We use tangent: $\tan(\theta) = \frac{\text{opposite}}{\text{adjacent}}$
Here, $\theta = 40^\circ$, adjacent side $QR = 18$, opposite side $PR$.

Step2: Rearrange to solve for PR

$PR = QR \times \tan(40^\circ)$

Step3: Calculate the value

$\tan(40^\circ) \approx 0.8391$, so $PR = 18 \times 0.8391 \approx 15.1$

Answer:

$15.1$
