Take the same problem from Lab $2$ and write a program that uses the variable a to contain the length of one leg, c the length of the hypotenuse, and b the calculated missing leg length. Use $17$ for a$,39$ for c$.$ Print b after you calculate it$.$

Use the equasion a$**2+$ b$**2=$ c$**2$ where a and b are the length of the legs and c is the length of the hypotenuse.
