Okay, so first time on the site. Let's hope this goes well, lol.
The question: Find, correct to the nearest degree,the three angles of the triangle with the given vertices.
The vertices: A(1,0), B(3,6), C(-1,4)
So I tried to start it out. Drew it because visuals rock. Then I found the distances between the points.
AB=
BC=
CA=
That's about as far as I was able to go. Any help is appreciated. Thanks!

Do you know the cosine rule? Since you know the lengths of the sides of the triangle, that will enable you to calculate the angles.
Okay, I finally realized what I was missing. There was a whole section of notes I was skipping over that had the formulas I was looking for. Same one Plato gave me but with the notation that I needed to remember how to find the vectors for BA and BC. Thanks guys!!!
