This solves Side-Angle-Side Triangles
Law of Cosines
a*a = b*b + c*c - 2*b*c*(Cos(A))
And the Law of Sines:
a/(Sin(A)) = b/(Sin(B)) = c/(Sin(C))
To Check Answer Let b = 6.21 ** A = 61 degrees ** c = 9.62
Answers should be a = 8.5547211 ** B = 39.412533 ** C = 79.587466872
Enter Here: Enter Length of Side b Here
Enter Here: Enter Angle A Here in Degrees (Less than 180 degrees)
Enter Here: Enter Length of Side c Here

This solves Angle-Side-Angle Triangles
Law of Cosines
a*a = b*b + c*c - 2*b*c*(Cos(A))
And the Law of Sines:
a/(Sin(A)) = b/(Sin(B)) = c/(Sin(C))
The Sum of the Angles must be less than 180 degrees
To Check Answer Let A = 29 degrees ** c = 2 ** B = 60 degrees
Answers should be Angle C = 91 ** a = .96976694 ** b = 1.7323146
Enter Here: Enter Angle A Here in Degrees (Less than 90 degrees)
Enter Here: Enter Length of Side c Here
Enter Here: Enter Angle B Here in Degrees (Less than 90 degrees)
