WebUsing the Law of Sines to Solve Oblique Triangles In any triangle, we can draw an altitude, a perpendicular line from one vertex to the opposite side, forming two right triangles. It would be preferable, however, to have methods that we can apply directly to non-right triangles without first having to create right triangles. WebThe law of sines is based on the proportionality of sides and angles in triangles. The law states that for the angles of a non- right triangle, each angle of the triangle has the same ratio of angle measure to sine value. sin(A) a = sin(B) b = sin(C) c Substitute the known values into the law of sines to find B. sin(B) 5 = sin(15) 4 iron in real life
