Design and write a program to calculate the third angle and the other two sides of a triangle.
The input to the program is
the length of one side a (unit not important)
the sizes of the two angles adjacent to that side B, C degrees
An important point that your program must deal correctly with:
The C++ trigonometric functions for sine, cosine and tangent
all expect their arguments (parameters) to be angles measured in radians, not in degrees.
