Trigonometry how to calculate angles

WebApr 24, 2024 · Using the previous triangle, you would divide 5 by 13, for a cosine of 0.384. On your calculator, input the value of either your sine or your cosine. Then press "inv." This should give you the angle associated with that value. The angle associated with sin 0.923 or cos 0.384 is 67.38 degrees. WebTo solve an SSS triangle: use The Law of Cosines first to calculate one of the angles. then use The Law of Cosines again to find another angle. and finally use angles of a triangle add to 180° to find the last angle. We use the "angle" version of the Law of Cosines: cos (C) = a2 + b2 − c2 2ab. cos (A) = b2 + c2 − a2 2bc.
