WebMar 3, 2024 · The formula for finding the total measure of all interior angles in a polygon is: (n – 2) x 180. In this case, n is the number of sides the polygon has. Some common polygon total angle measures are as follows: [2] The angles in a triangle (a 3-sided polygon) total 180 degrees. The angles in a quadrilateral (a 4-sided polygon) total 360 degrees. WebSecant (sec) - Trigonometry function. (See also Secant of a circle ). In a right triangle, the secant of an angle is the length of the hypotenuse divided by the length of the adjacent side. In a formula, it is abbreviated to just 'sec'. Of the six possible trigonometric functions, secant, cotangent, and cosecant, are rarely used. grasim annual report 2020
