Please help thank you

Answer 1

The sine of an angle is the length opposite side of the angle divided by the length of the hypotenuse.

The cosine of an angle is the length of the adjacent side of the angle divided by the length of the hypotenuse.

We are looking for the sine and cosine of angle A. First, let's find the sine.

The length of the side opposite of angle A is 48. The length of the hypotenuse is 50.

Thus, $sin(A)= \dfrac{48}{50}$

The length of the side adjacent to angle A is 14. The length of the hypotenuse is 50.

Thus, $cos(A)= \dfrac{14}{50}$

Your answer is the second choice. I hope this helps! :)
