It relates the lengths of the sides of a triangle to the cosine of one of its angles. The formula for the Law of Cosines is x cos (C), where a, b, and c are the lengths of the sides and C is the angle opposite side c. To use the Law of Cosines, you need to have either lengths of two ...Solving SSA Triangles. "SSA" means "Side, Side, Angle". " SSA " is when we know two sides and an angle that is not the angle between the sides. To solve an SSA triangle. use The Law of Sines first to calculate one of the other two angles; then use the three angles add to 180° to find the other angle; finally use The Law of Sines again to find ...Choose the correct answer below. O A. The statement does not make sense because the Law of Sines can be used as it requires the measures of at least two angles of an oblique triangle. O B. The statement makes sense because knowing all three angles does not determine a unique triangle. There are an infinite number of similar triangles that share ...To solve a triangle when we know two sides and the included angle, we will need a generalization of the Pythagorean theorem known as the Law of Cosines. In a right triangle, with C = 90∘ C = 90 ∘, the Pythagorean theorem tells us that. c2 = a2 +b2 c 2 = a 2 + b 2.Final answer.
