Question

answer
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 \(40\) and the hypotenuse is \(41\).

Step3: Calculate \(\sin A\)

\(\sin A=\frac{40}{41}\)

Answer:

\(\frac{40}{41}\)
