We are given the following triangle
We are interested in calculating the sine of angle B. Recall in a right triangle, the sine of angle is given by the expression
![\sin (\text{angle)}=\frac{\text{length of the opposite side}}{length\text{ of the hypotenuse}}](https://img.qammunity.org/2023/formulas/mathematics/college/90dt4ji8kvzol0vqn5bn2yk5dggsq8avd7.png)
Here, we have angle B as reference. With respect to angle B, the opposite side would be side AC. Also, in the triangle, the hypotenuse is side AB. So we have
![\sin (B)=(35)/(37)](https://img.qammunity.org/2023/formulas/mathematics/college/561jmwfor9belb2socmrhp1ucjomjiyisj.png)
