WebFinal answer. Transcribed image text: Using the Law of Sines to solve for all possible triangles if ∠B = 50∘,a = 109,b = 49. If no answer exists, enter DNE for all answers. ∠A is degrees ∠C is degrees c = Assume ∠A is opposite side a,∠B is opposite side b, and ∠C is opposite side c. Previous question Next question. WebWhen you solve your equation using arcsin, you're getting the acute angle at vertex C 1, the one labeled as θ in the diagram. The relationship between θ and the angle at vertex C is θ + C = 180. The reason: triangle A C C 1 is isosceles so ∠ A C C 1 = ∠ C C 1 A = θ. Therefore θ and C are supplementary angles.
WebUse the Law of Sines to get one possible angle A: sin(A)/a=sin(C)/c sin(A)/5.6=sin(31)/3.9 sin(A)=5.6sin(31)/3.9 A=arcsin(5.6sin(31)/3.9)=47.6924 Subtract 31 (C) and this angle … WebMar 27, 2024 · Looking at a triangle, the lengths a,b, and c are opposite the angles of the same letter.
