If c represents the length of the hypotenuse of a right triangle and a and b represents the lengths of the legs, solve for the length of the missing side in each case. Express your answers in in simplest radical form and then as a decimal to the nearest tenth.
a=9 and c=18
9^2+b^2=18^2
81+b^2=324
i need to subtract the 81 from 324 giving me 243 i need to find the 2 perfect squares that go into it.
