The best thing to do will be to work through the steps for angle B. If we get 29.7Â° , then we will be fairly confident that we found both the correct answers. If we get 29.7Â° , then we will be fairly confident that we found both the correct answers.... If you mean the angle that P1 is the vertex of then using the Law of Cosines should work: arccos ((P 12 2 + P 13 2 - P 23 2 ) / (2 * P 12 * P 13 )) where P 12 is the length â€¦

If you mean the angle that P1 is the vertex of then using the Law of Cosines should work: arccos ((P 12 2 + P 13 2 - P 23 2 ) / (2 * P 12 * P 13 )) where P 12 is the length â€¦... Hence the tangent of an obtuse angle is the negative of the tangent of its supplement. Note that tan 0 Â° = 0 and tan 180Â°= 0 since the sine of these angles is 0 and that tan 90Â° is undefined since cos 90Â°= 0.

27/09/2010Â Â· To calculate angles using trigonometry, use a graphing or scientific calculator with sine, cosine and tangent buttons. Improve your math skills by learning to calculate â€¦... A tangent to a circle forms a right angle with the circle's radius, at the point of contact of the tangent. Also, if two tangents are drawn on a circle and they cross, the lengths of the two tangents (from the point where they touch the circle to the point where they cross) will be the same.
