It's the old "5 - 12 - 13" triangle in disguise.
Anyway, 6^2 + 2.5^2 = 42.25 = 6.5^2
The missing side is 6.5
a^2 + b^2 = c^2
Substitute:
6^2 + 2.5^2 = c^2
Then solve
Ok Corey--
Use the Pythagorean Theorem---hypt^2 = side 1^2 + side 2^2
so hypt = sqrt(36 + 6.25) = sqrt(42.25)..just put this into your calculator for the answer.
question is not clear.
Its a right triangle. The height os 6 and the base is 2.5
