Question

find the sine of ∠s. simplify your answer and write it as a proper fraction, improper fraction, or whole number. sin(s) =

Explanation:

Step1: Recall sine definition

For $\angle S$, $\sin(S) = \frac{\text{opposite side}}{\text{hypotenuse}}$

Step2: Identify sides

Opposite side to $\angle S$ is $QR=45$, hypotenuse is $SR=53$.
$\sin(S) = \frac{45}{53}$

Answer:

$\frac{45}{53}$
