You can put this solution on YOUR website!
First, triangles (as you know) have three sides, but they also have three angles.
All three of the angles always add up to 180 degrees! (This is a key concept).
So if you have a right triangle, you have a 90, and you said you have one more -- say for example, a 20 degree angle. That would leave you with a 70 degree angle as the third one. So that has a definite shape, the only question left is whether you have a huuuuuge 20-70-90 triangle, or a teeny weenie one.
You say you have one side - bingo! You have to do SOH-CAH-TOA to solve for the other two. If you had given me the numbers (including that angle) I could have solved it for you.
Hope the theory helps.
