# How do you find angles A, B, and C if in triangle ABC, #a=12#, #b=15#, and #c=20#?

To solve the for the angles when we have the lengths of all three sides, we use the law of cosines.

Hope this helps!

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
