If you are solving for x.
y=2.5x+5
you subtract 5 from both sides.
-5=2.5x
then divide both sides with 2.5
-5/2.5 2.5/2.5
the 2.5s will cancel each other out.
x=-2
As shown , using trigonometry, sine and cosine will solve all the problems. remember, soh cah toa.
Sine is opposite over hypotenuses.
Cosine is adjacent over hypotenuses.
And tangent is opposite over adjacent.
