If that ratio is 0.866 then acos (0.866) = 30°. arctangent (atan) — gives...
WebThe angles always add to 180°: A + B + C = 180° When you know two angles you can find the third. 2. Law of Sines (the Sine Rule): a sin (A) = b sin (B) = c sin (C) When there is an angle opposite a side, this equation comes to the rescue. Note: angle A is opposite side a, B is opposite b, and C is opposite c. 3. Law of Cosines (the Cosine Rule): WebAug 25, 2013 · Declare 3 double type variables, each representing one of three sides of a triangle. Prompt the user to input a value for the first side, then. Set the user’s input to the variable you created representing the first side of the triangle. Repeat the last 2 steps twice more, once for each of the remaining 2 sides of the triangle.
