Question

Sin 3/5 4/5 3/4 5/4

Answer 1

Answer:

$\boxed{\frac{3}{5}}$

Step-by-step explanation:

The trigonometric functions are described as follows:

$sin = \frac{opposite}{hypotenuse}\\\\cos = \frac{adjacent}{hypotenuse}\\\\tan = \frac{opposite}{adjacent}$

Using reference angle ∠A, use the sin trigonometric function. This will be the side opposite (cannot be the hypotenuse) of ∠A over the side adjacent (cannot be the hypotenuse).

The side opposite of ∠A is 3. The hypotenuse of the triangle is 5.

$\boxed{\frac{3}{5}}$  is the final answer!
