WebThe Law of Tangents is a statement involving the tangents of two angles in a triangle and the lengths of opposite sides. The Law of Tangents state: a-b/a+b = tan [1/2 (A-B)]/tan [1/2 (A+B)] ( 13 votes) jhou 9 years ago If you search the law of sines on the internet, it'll mostly give you A/sin (a) = B/sin (b) = C/sin (c). WebNote that the tangent of a right angle is listed as infinity. That’s because as the angle grows toward 90°, it’s tangent grows without bound. It may be better to say that the tangent of 90° is undefined since, using the circle definition, the ray out from the origin at 90° never meets the tangent line. Exercises 29.
