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.
What is the measure of interior angle of a regular polygon with 7 side? Going round you turn 1/7th of a full revolution (2*pi/7) at each corner. (Or 360/7 degrees at each corner if you prefer units of degrees). The interior angle is pi minus thisâ¦ amount of turn (or 180 degrees minus this amount of turn if you prefer).
