Question

sin a
c
32
b
24
40
a
find sina
32/24
24/40
24/32
32/40

Explanation:

Step1: Recall the sine function definition

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

Step2: Identify the sides

For angle $A$, the side opposite to angle $A$ is $BC = 32$, and the hypotenuse $AC=40$.

Step3: Calculate $\sin A$

Using the formula $\sin A=\frac{\text{opposite}}{\text{hypotenuse}}$, we substitute the values: $\sin A=\frac{32}{40}$.

Answer:

$\frac{32}{40}$
