Question

find: sin a
the figure is not drawn to scale.

Explanation:

Step1: Recall the sine formula

In a right - triangle, $\sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}$.

Step2: Identify the sides for angle \(A\)

For angle \(A\), the opposite side is \(7\) and the hypotenuse is \(25\).
So, $\sin A=\frac{7}{25}$.

Answer:

$\frac{7}{25}$
