Start by identifying the hypotenuse of the right triangle. Then find the sides that are opposite and adjacent to ∠C.
3/5=0.60
Practice makes perfect
For the given right triangle, we want to write the ratio for the sine of ∠C. Let's start by identifying the hypotenuse of the triangle and the sides that are opposite and adjacent to ∠C.
We see that the length of the hypotenuse is 25. The length of the side adjacent to ∠C is 20 and the length of the side opposite to ∠C is 15. With this information, we can find the desired ratio.
