WebT HE LAW OF SINES allows us to solve triangles that are not right-angled, and are called oblique triangles. It states the following: The sides of a triangle are to one another in the same ratio as the sines of their opposite angles. a: b: c = sin A : sin B : sin C. Specifically, side a is to side b as the sine of angle A is to the sine of angle B. WebRecall the Law of Sines, which states that if ABC is a triangle whose sides are a, b, c then In Substitute these values in the Law of Sines to evaluate y. Use a calculator to evaluate y to four decimal places. Step 5 Using the Law of Sines and y = 27 in ΔACB, speed =. distance time 13 = distance 45 45 60 (distance)DC = 13 × = 9 39/ 45 45 60
