Write a C++ program

Scalene Triangle a)A scalene triangle has no equal angles or no equal sides. Create a program that request the use type in the lengths of the three sides of the scalene triangle. Calculate and display the perimeter and area b) Calculate the angle across from the largest side as shown below and display that result. Note: you will need #include ; and also note that C++ only operates in radians. 1 degree = radians O a e C Heron's Formula half of the A perimeter S = a+b+c 5: 2 Area =J5(saxs-b(s-c) b Angle C con == cos" (a+b = c)
