Two sides and an angle (SSA) of a triangle are given. Determine whether the given measurements produce one triangle, two triangles, or no triangle at all. Solve each triangle that results. Round lengths to the nearest tenth and angle measures to the nearest degree.C = 35°, a = 18.7, c = 16.1
A. A1 = 103°, B1 = 42°, b1 = 27.4; A2 = 7°, B2 = 138°, b2 = 3.4 B. A1 = 42°, B1 = 103°, b1 = 27.4; A2 = 138°, B2 = 7°, b2 = 3.4 C. no triangle D. A = 42°, B = 103°, b = 27.4
Solve the problem.When three parallel lines are crossed by two or more lines (transversals), the lengths of corresponding segments are proportional (see the following figure).
