sina
find sina
32/24
24/40
24/32
32/40

Explanation:

Step1: Recall the sine formula

In a right - triangle, \(\sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}\). For angle \(A\), the side opposite to angle \(A\) is \(BC = 32\), and the hypotenuse is \(AC=40\).

Step2: Calculate \(\sin A\)

Using the formula \(\sin A=\frac{BC}{AC}\), substitute \(BC = 32\) and \(AC = 40\). So, \(\sin A=\frac{32}{40}\).

Answer:

\(\frac{32}{40}\) (the option with \(32/40\))
