A right triangle has a hypotenuse that measures 73 mm and one side that measure 48 mm. What is the length of the remaining side of the triangle?

The formula we want to use is a^{2} + b^{2} = c^{2}

c is the longest side, or the hypotenuse while a and b are the shorter sides.

So, we have a^{2} + 48^{2} = 73^{2}

That gets us a^{2} + 2304 = 5329

Subtract 2304 on each side and we get a^{2} = 3025

Now we need to take the square root of each side, which gives us a final answer of a = 55mm
