Question

find d (1 point) 30 m 39° ○ 47 ○ 18.9 ○ 19.5 ○ 27.5

Explanation:

Step1: Identify trigonometric ratio

We use sine: $\sin(\theta)=\frac{\text{opposite}}{\text{hypotenuse}}$, where $\theta=39^\circ$, opposite side is $d$, hypotenuse is 30 m.

Step2: Rearrange to solve for d

$d = 30 \times \sin(39^\circ)$

Step3: Calculate the value

$\sin(39^\circ)\approx0.6293$, so $d\approx30\times0.6293=18.879$

Answer:

18.9
