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: $\tan(\theta)=\frac{\text{opposite}}{\text{adjacent}}$
Here, $\theta=35^\circ$, opposite side is $QR$, adjacent side $RS=5.8$.

Step2: Rearrange to solve for QR

$QR = RS \times \tan(35^\circ)$

Step3: Calculate the value

$\tan(35^\circ)\approx0.7002$, so $QR\approx5.8\times0.7002$
$QR\approx4.06116$

Step4: Round to nearest tenth

Round $4.06116$ to 1 decimal place.

Answer:

$4.1$
