Law of sines solve each triangle
WebA = sin-1[ (a*sin (b))/b] Assuming that a, b and c are the 3 sides of the triangle opposite to the angles A, B and C as shown in the figure below, the law of sines states that: For the calculation of the three sides (a, b and c) these formulas are applicable: a = b*sin (A)/sin (B) a = c*sin (A)/sin (C) b = a*sin (B)/sin (A) b = c*sin (B)/sin (C) WebSolution for In Problems 33–42, solve each triangle using either the Law of Sines or the Law of Cosines.33.
