create a C++ program:

Given three sides

Find the missing angles one by one of an oblique triangle. 

formula and sample problem:

 

Solution of Case 4: Given three sides (by Cosine law)
Example:
1.
Given:
a = 30.3, b = 40.4, c = 62.6
Solve AABC
Solution:
Solve for the 1" angle by cos law
b +c
-a
a = cos
2bc
(40.4) +(62.6)-(30.3)
2(40.4)(62.6)
a = cos
a = 23°40
Solve for the 2 angle by cos law
a? +c-b?
B= cos"
2ac
(30.3) +(62.6) -(40.4)
2(30.3)(62.6)
B= cos
B= 32 21
60

Solve for the 3" side using Angle Sum formula
Y = 180° - (a + B)
y = 180° - (23°40' + 32°21')
y = 123°59
