Solving Real World Problems Using the Law of Sines
WebJan 2, 2024 · Solution Using the Law of sines, we can say that: sin112 ∘ 45 = sin B 24 0.9272 45 ≈ sin B 24 24 ∗ 0.9272 45 ≈ sinB 0.4945 ≈ sinB Then, we find sin − 1(0.4945) ≈ 29.6 ∘. Remember from Chapter 3 that there is a Quadrant II angle that has sinθ ≈ 0.4945, with a reference angle of 29.6 ∘. So, ∠B could also be ≈ 150.4 ∘. WebThe Law of Sines Formula is, a S i n A = b S i n B = c S i n C Solved Examples Question 1: In a triangle ABC, the side lengths AB = 5 cm; BC = 3 cm and CA = 4 cm. The angle opposite to the side A is 60 o. Calculate the other unknown angles? Solution: Given, AB = a = 5 cm BC = b = 3 cm CA = c = 4 cm A = 60 o The law of sines formula is, a s i n A = WebApr 11, 2024 · The law of sine is defined as the ratio of the length of sides of a triangle to the sine of the opposite angle of a triangle. The law of sine is also known as Sine rule, Sine law, or Sine formula. Law of sine is used to solve traingles. a, b, and c are sides of the above triangle whereas A, B, and C are angles of above triangle. cummings slates perth
