Answer 1

Sine is opposite/hypotenuse. Opposite of angle S is line QR, which is unknown. Therefore start with the Pythagorean Theorem to find QR. For simplicity, I'll use x as a variable for QR.


`x^(2)`+60²=68²

`x^(2)`=68²-60²

`x^(2)`=4264-3600

`x^(2)`=1024
x=
`√(1024)`
x=32

So QR is 32. Therefore, sin S is 32/68, which simplifies to 8/17.

Answer 2

first you have to do puthagorean theorm to find the missing leg which is QR then to find sinS you go opposite over hypotenuse. simplify if needed.
