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.
But for any regular polygon, the sum of the measures of the exterior angles is 360 deâ¦grees. You can use this information to find out the measure of an interior angle, because the sum of the measures of each interior/exterior pair of angles is always 180 degrees. So to find the answer to this problem, divide 360 by 7.
