Find angle $\alpha$. calculator for radians, sine, cosine & tan for any angle by Russell Kightley Media. 300°? All three 'Angular' Bisectors (a line that divides an angle in two) of any triangle always meet at the same point, which is the centre of its inscribed circle (Fig 3). (From here solve for X).By the way, you could also use cosine. If you know the length of all three sides you can establish the lengths of all hypotenuses and their angles. Specifically, they are the inverses of the hyperbolic sine, cosine, tangent, cotangent, cosecant and secant functions. A similar question is, how does the calculator figure out the value of sin, cos, etc.? They are widely used in all sciences that are related to geometry, such as navigation, solid mechanics, celestial mechanics, geodesy, and many others. Graphing sine, cosine and tangent is nuanced. tangent of alpha = opposite leg / adjacent leg. Or you could ask, what did people do before the calculator was invented, i.e.     a² = b² + c² - 2.b.c.cos(A) are all described in the Definitions page of this web site.     Cotangent of an angle: cot = 1/tan. In those formulas, the opposite leg is opposite of alpha, the hypotenuse opposite of the right angle and the remaining side is the adjacent leg. The Sine of angle θis: 1. the length of the side Opposite angle θ 2. divided by the length of the Hypotenuse Or more simply: sin(θ) = Opposite / Hypotenuse The Sine Function can help us solve things like this: Sine, Cosine and Tangent are the main functions used in Trigonometry and are based on a Right-Angled Triangle. This will provide us a common, basic understanding of the graphs of the three fundamental Trigonometric functions. All three 'Medians' of any triangle always meet at the same point, which is the centre of gravity of the triangle (Fig 4). To calculate the angle of a right triangle, sine cosine tangent formula is used.
