Length of a side of triangle (with the length of another side and its two angles known)

When the length (a) of a side and its two angles (B, C) for a trangle are known as shown in figure, lengths (b, c) of other two sides can be determined by the sine theorem.

Sum of interior angles of a triangle is 180 degrees, thus,

A = 180-B-C

Since a/sin(A) = b/sin(B) = c/sin(C),

b = a*sin(B)/sin(A), c = a*sin(C)/sin(A)

*** 참고문헌[References] ***

b = a*sin(B)/sin(180-B-C)
