Chapter 12, Problem 11STP

To determine

To find: the value of $\sin B$ .

Answer to Problem 11STP

The value of $\sin B$ is $\frac{5}{13}$ .

Explanation of Solution

Given information:

From the figure provided in the question, it can be observed that the hypotenuse of triangle is $13$ and the legs is $5$ .

Calculation: to find the value of $\sin B$ , divide the legs of triangle by the hypotenuse of triangle,

  $\begin{array}{l}\sin B=\frac{\text{legs}}{\text{hypotenuse}}\\ \sin B=\frac{5}{13}\text{ [substitute]}\end{array}$

Thus, the value is $\frac{5}{13}$ .
