Problem 1 Points: 8 Design and implement a program that prompts the user for the length of the sides a, b, and c, of a triangle and performs the following operations: 1. Determine the type of triangle (acute, obtuse, right angle, or equilateral). (Hint: compute angles) 2. Determine the area of the triangle. (Hint: the area of a triangle can be computed from its sides using the formula Area s (s a) (s b) (s c) where s is half the sum of the sides of a triangle S Be sure to format the output and give any error messages
