How to find the value of Cos 120 0. As mentioned in the solution given below, 120° can be represented in terms of two angles i.e. either 90° or 180°. We can show that 120 degrees can be represented in two angles, whose value can be taken from trigonometry table. 90 degree and 180 degree. 180° – 60° = 120° ———– (1)

Table of cosines are the counted values of angles cosines noted in the table from 0° to 360°. Using a table of cosines you can make calculations even if not at hand will be the scientific calculator. To find the cosine of the angle is sufficient to find the value in the table.

The value of cos 120 degrees is -0.5. Cos 120 degrees in radians is written as cos (120° × π/180°), i.e., cos (2π/3) or cos (2.094395. . .). In this article, we will discuss the methods to find the value of cos 120 degrees with examples. Cos 120°:-0.5; …

2023年1月24日 · The value of cos 120° is -1/2 or -0.5 as it lies in the 2nd quadrant where cosine is negative. The formula of cosine is, cos x = (adjacent side) / (hypotenuse). Here, the adjacent side is adjacent to angle x, and the hypotenuse is the triangle’s longest side.

Value of Cos 120 is -½. Cos 120 degrees is equivalent to minus half, and is often written as (- ½ ) or (-0.5). Cos, in trigonometric expressions, is identified as one of the main functions that often conforms with the relationship between the angles and sides present in a right-angled triangle. Thus, in a right-angled triangle, there are:
