Question

Find the trigonometric ratio and write answer as simplified fraction

Answer 1

Answer:  3/5

Explanation:

For angle A, the side furthest from here is BC = 15. This is the opposite side for this reference angle.

The hypotenuse is AC = 25, which is the longest side of any right triangle (always opposite the 90 degree angle).

The sine ratio involves dividing the opposite over hypotenuse.

So,

sin(angle) = opposite/hypotenuse

sin(A) = BC/AC

sin(A) = 15/25

sin(A) = (3*5)/(5*5)

sin(A) = 3/5
