Question

score: 9/10 current time: 139.2 find: sin b the figure is not drawn to scale answer 84/85 84/13 13/85 13/84

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 $13$ and the hypotenuse has length $85$.

Step2: Calculate $\sin B$

$\sin B=\frac{13}{85}$

Answer:

$\frac{13}{85}$
