3) PE osa 03 as Triangle Function) Create a function that determines if any set of three integers form a triangle. Your function should take three integers as arguments and return the integer lif the set of three integers do form a right triangle and return e otherwise. Test your function in a program. 4) PE 05a 04 (Function fox) Write a function for f(x) and test it in a program. Evaluate the function for several values. The function should receive and return data type double. 7x 4 f(x) X2 1 5) PE 05a 05 (Hypotenuse) Write a function that calculates the hypotenuse of a triangle. Test your function in a program that reads the coefficients from the keyboard with scanf as data type double using the conversion specifier xlf. Create your function using the sqrt(x) and pow(x,n)functions from the math, h header. c hyp(a, b) a2 b2 COP2270 by TCunnyngham gmo 14 jpg gmo 13.jpg gmo 12.jpg
