Right away,
Recall that , so . We're told that , for which we expect to have and so we take the positive square root. Also recall that 3-4-5 is a Pythagorean triple. Then
We have everything we need to find the remaining trig ratios. With the help of double angle identities, we get
-2+7=5
5+7=12
12+7=19 so,
7n-9
