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 Web2 dagen geleden · You know the lengths of the two sides of a triangle and the included angle.
