Philip Carret, who wrote The Art of Speculation (1930), believed âmotiveâ was the test for determining the difference between investment and speculation. âThe man who bought United States Steel at 60 in 1915 in anticipation of selling at a profit is a speculator.
The formula for finding the total measure of all interior angles in a polygon is (âânââ â 2) x 180, where âânââ is the number of sides, as well as the number of angles, the polygon has. Some common polygon total angle measures are as follows: The angles in a triangle (a 3-sided polygon) total 180 degrees.
The interior angles of a regular polygon are each 120Â°. Calculate the number of sides. The interior angles are 120Â°, so the exterior angles are 180Â° - 120Â° = 60Â°. The exterior angles add up to 360Â°, so if we divide 360Â° by 60Â° we find there are 6 exterior angles. Therefore, there are 6 sides (it is a hexagon).
