USE THE INFORMATION TO DECIDE IF TRIANGLE ABC IS ACUTE, RIGHT, OR OBTUSE

AC = 13

BC = sq rt. 34

CD = 3

I know the answer is obtuse but I don't know how to get there. The sq rts threw me off

Your example cannot make a triangle because the longest side (13) is longer than the sum of the other two sides (5.83 + 3 = 8.31).

There is a rule that says that if you are given any two sides of a triangle, A and b, the third side must be less than A + B and greater than |A - B|
