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
[tex]\sin (\text{angle)}=\frac{\text{length of the opposite side}}{length\text{ of the hypotenuse}}[/tex]
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
[tex]\sin (B)=\frac{35}{37}[/tex]
