Explanation:

Step1: Recall the sine formula

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

Step2: Identify the sides relative to angle \(A\)

For angle \(A\), the opposite side is \(48\) and the hypotenuse is \(60\)

Step3: Calculate \(\sin A\)

\(\sin A=\frac{48}{60}\)

Answer:

\(\frac{48}{60}\)
