timed problem
score: 5/10 current time: 79.3
find: sin b
the figure is not drawn to scale
answer
72/65
65/72
72/97
65/97

Explanation:

Step1: Recall sine - definition

In a right - triangle, $\sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}$. For angle $B$, the side opposite to angle $B$ has length $65$ and the hypotenuse has length $97$.

Step2: Calculate $\sin B$

$\sin B=\frac{65}{97}$

Answer:

$\frac{65}{97}$
