Question

score: 1/10 current time: 37.3 find: sin b the figure is not drawn to scale answer 18/80 80/82 18/82 80/18

Explanation:

Step1: Recall sine - definition

In a right - triangle, $\sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}$. For angle $B$, the side opposite to angle $B$ is $18$ and the hypotenuse is $82$.

Step2: Calculate $\sin B$

$\sin B=\frac{18}{82}$.

Answer:

$\frac{18}{82}$
