Solving Radical Equations (quadratic)
I am given a right triangle. One leg is a=7mm and the hypotenuse is c=7.4mm.
It says to find the length of the unknown side b of the given triangle and to also give the exact length and a one decimal place approximation.

We use the Pythagorean theorem:

So the other leg b is 2.4mm.
That is the exact value.
