Write a Python function called "triangle. py with three inputs and three outputs. The inputs are the lengths of the three sides of a triangle and the outputs are the angles in degrees of side opposite to the length. If the user fails to enter a value for the length of one, two or three sides, the function needs to prompts the user for the unknown lengths. For the sides of a triangle (a, b, and c), use the law of cosines to find the angles (A, B, and C). I. 2ab cos(A) = me-a2 2bc cos(B) = c'+a2-b2 2ac Besides the function output, use print statements to print the sides a, b, and c and the angles in degrees A, B, and C
