HELP!!!!!!!!!!!!!! I learned this two years ago and I don't remember how to do this anymore!!!!!!

So remember the acronym "SOH CAH TOA"

Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent

Opposite = Side that doesn't touch the angle
Adjacent = Side that touches the angle
Hypotenuse = Side that is across from the right angle

So we see that side a doesn't touch angle $\alpha$ , hence making it the opposite side. And we see that side b is across from the right angle, making it the hypotenuse. <u>Using this info, $\sin \alpha = \frac{a}{b}$ </u>

So we already know from part A that side b is the hypotenuse. And also since side c touches the angle, it is the adjacent.<u> Using this info, $\cos \alpha = \frac{c}{b}$ </u>
