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): WebIn trigonometry we use the functions of angles like sin, cos and tan. It turns out that angles that have the same reference angles always have the same trig function values (the sign may vary). So for example sin(45) = 0.707. The angle 135° has a reference angle of 45°, so its sin will be the same. Checking on a calculator:

WebThe angle measurement in degrees is θ ≈ 53.1 ∘ θ ≈ 180 ∘ − 53.1 ∘ ≈ 126.9 ∘ Analysis Note that a calculator will only return an angle in quadrants I or IV for the sine function since that is the range of the inverse sine. The other angle is obtained by using π − θ. WebTrigonometry angles are the angles given by the ratios of the trigonometric functions.
