) Create a data file (using Notepad, perhaps) containing the vahues shown below (plus add 4 more lines of your choice) and then write a C++ program as follows: . Read the data file (you can assume that it has exactly 8 lines with 3 numbers per line) . Calculate the three angles using the law of cosines (assume that the sides are valid) . Write the results to an output data file. The results should include headings and 2 digits after the decimal point for all values. An example is shown below. .Print the program and the two data files. Input data file: 20 15 10 5 12 13 10 10 14.142 50 60 70 Sides a, b, and c for Triangle 1 Pick values for 4 more valid triangles Output data file Side a 20.00 Side b 15.00 Side c 10.00 Angle A (deg) 104.48 Angle B(deg) Angle C(deg) 46.57 28.96
