the question is: if you have the side of a right triangle and the angle opposite to it, can you find all the side lengths of the triangle? (assuming it's a right triangle)
this is what I did, where A is the side you know, B is the base of the triangle which you don't know, and X is the angle you know.
tan(x) = a/b b(tan(x)) = a b = a/tan(x)
I checked it and it seemed to be correct... Did I do this right? I had to figure out how to use tan myself, me teacher didnt show me how soo |
