Question

find: sin b

Explanation:

Step1: Recall the sine formula

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

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

For angle \(B\), the opposite side is \(20\) and the hypotenuse is \(25\).

Step3: Calculate \(\sin B\)

\(\sin B=\frac{20}{25}\)

Answer:

\(\frac{20}{25}\)
