$\sin\theta=(b)/(c)\ therefore\ b=c\cdot\sin\theta\n\n\cos\theta=(a)/(c)\ therefore\ a=c\cdot\cos\theta$

$b=32\cdot\sin55^o=\sin55^o\cdot32\n\na=32\cdot\cos55^o=\cos55^o\cdot32$

How do you factor 2n^2+3n-9

Answers

Find the factors that multiply to give 2n^2 and -9 but add to give 3n.
2n and n give 2n^2
-3 and 3 give -9
2n*3=6n ... (1)
n*(-3)=-3n ... (2)
(1)+(2)=3n
Group the factors that do not have an effect/interaction to each other from the above.
That is, 2n and -3, and n and 3

2n^2+3n-9=(2n-3)(n+3)
