Webb24 jan. 2024 · Since we are already aware of the values of trigonometric angles for sin, cos and tan from 0 to 90. We will use the formula to find the value of cos 120. Using cos (180° – θ) = – cosθ 1. cos 120° = cos (180° – 60°) = -cos 60 = -1/2. Using cos (90° + θ) = – sinθ 1. cos (90° + 30°) = – sin30° = -1/2. Trigonometrical Table: Cos 120 WebbCos 45 degrees. In a 45 degrees right-angled triangle, the cosine of angle 45° is a value representing the ratio of the length of the adjacent side to the length of the hypotenuse (of angle θ). In trigonometry, we write the cosine of angle 45° mathematically, and its exact value in fraction form is 1/√2. Therefore, we write it in the ...
