Question

find: sin b the figure is not drawn to scale answer $\frac{7}{25}$ $\frac{24}{7}$ $\frac{7}{24}$ $\frac{24}{25}$

Explanation:

Step1: Recall sine - ratio definition

In a right - triangle, $\sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}$. For angle $B$, the side opposite to angle $B$ is $7$ and the hypotenuse is $25$.

Step2: Calculate $\sin B$

$\sin B=\frac{7}{25}$

Answer:

$\frac{7}{25}$
