Question

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

Explanation:

Step1: Identify trigonometric ratio

We use tangent: $\tan(\theta) = \frac{\text{opposite}}{\text{adjacent}}$

Step2: Substitute known values

$\tan(69^\circ) = \frac{8}{QR}$

Step3: Rearrange to solve for QR

$QR = \frac{8}{\tan(69^\circ)}$

Step4: Calculate the value

$\tan(69^\circ) \approx 2.6051$, so $QR \approx \frac{8}{2.6051} \approx 3.0$

Answer:

3.0
