Answer

$\boxed{\sin A = \frac{3}{5}}$

Steps

Step 1 ：Recall the definition of sine in a right triangle: $\sin A = \frac{\text{opposite side}}{\text{hypotenuse}}$

Step 2 ：In our case, the side opposite angle A is 3 and the hypotenuse is 5, so $\sin A = \frac{3}{5}$

Step 3 ：$\boxed{\sin A = \frac{3}{5}}$
