Question 3080
Use the pythegorean theorem to solve the length of the diagonal side of a right triangle if the other two side of the triagle is know.

EX# Draw a right triangle and assume the diagonal is AC (unknown)
and the two sides known are AB=2 and BC=3

Using the pythegorean theorem: AB^2+BC^2=AC^2
                               2^2+3^2=AC^2
                                 4+9=AC^2
                                  13=AC^2
                      Therefore, AC=3.61.....by taking the sqrt(13)
