C programming with user-defined functions, including inputs. Thanks!

Area C Problem: Given three points (A, B, C) that will always create a triangle with a positive area, calculate the measures of its three internal angles and the areas of the three quadrilaterals (Area A, Area B, Area C) created when a perpendicular lines are connected from the incenter to each side of the triangle. For this assignment you will be required to implement the user-defined functions r Area A Area B A B. Example Execution #1: Enter x coordinate #1 -> 1.5 Enter Y coordinate #1 -> 1.5 Enter x coordinate #2 -> 2.8 Enter Y coordinate #2 -> 3.8 Enter X Coordinate #3 -> 1 Enter Y Coordinate #3 -> 6 Internal triangle angles: 35 48' 57.89", 111 14' 4.93", 32 56' 57.17" Area of quadrilaterals: 1.51, 0.33, 1.65 Example Execution #2: Enter x coordinate #1 -> -1 Enter Y coordinate #1 -> 3 Enter x coordinate #2 -> -2 Enter Y coordinate #2 -> -4 Enter x coordinate #3 -> 2 Enter Y Coordinate #3 -> -1 Internal triangle angles: 45 0' 0.00", 45 0' 0.00", 90 0' 0.00" Area of quadrilaterals: 5.18, 5.18, 2.14
