WebStep 1: Solve for the missing angle measure using the sum of the interior angles of a triangle. Thus, ∠B = 180° – ∠A + ∠C∠B = 180° – 54° + 58°∠B = 180° – 112°∠B = 68° Step 2: Use the Law of Sines to determine the unknown side measures. Thus, To find a using the side measure of b : 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. WebWe will use The Law of Sines to find angle L first: sin (L)/l = sin (M)/m sin (L)/7.6 = sin (125°)/12.4 sin (L) = (7.6×sin (125°))/12.4 sin (L) = 0.5020... L = 30.136...° L = 30.1° to one decimal place Next, we will use "the three angles add to 180°" to find angle N: N = 180° − 125° − 30.136...° N = 24.863...° N = 24.9° to one decimal place
