Write a function named hypotenuse () that accepts the lengths of two sides of a right triangle as the parameters a and b, respectively. This function should determine and return the hypotenuse, c, of the triangle. (Hint: Use Pythagoras theorem that c^2 = a^2 + b^2.) Include the function written above in working program. Make sure your function is called from main () and correctly returns a value to main(). Have main () display the value returned. Test the function by passing various data to it
