law of sins :)
sinA/a=sinB/b=sinC/c
*only used when you have pairs, an angle and the side opposite of it.
*setting up a proportion.
Ex: a civil engineer wants to determine the distance from points A and B to an inaccessable point C. from direct measurement -- AB=25m,
first you would draw a diagram and lable EVERYTHING. Then, choose your pairs. Finally set up a proportion.
(sin50/25)=(sin20/B)
cross multiply--Bsin50=25sin20
divide by sin50
B=11.162m
you would follow the same process to find side "a".
I still don't understand integral coefficients if anyone wants to help.

to solve for integral coefficients all you have to do is factor the given equation and the resulting X's will be your integral coefficients.
