SOLUTION: how are we supposed to find a side length in a right triangle if given one more angle and one side of the triangle? thank you!

Question 135809: how are we supposed to find a side length in a right triangle if given one more angle and one side of the triangle?
thank you!

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.
