![]() The inscribed polygon is divided into n triangles, and then half of that would mean dividing a full rotation by 2n. Unit Circle Game Pascals Triangle demonstration Create, save share charts Interactive simulation the most controversial math riddle ever. Math Gifs Algebra Geometry Trigonometry Calculus. It depends on the size of the circle, but in this case, where r = 1/2, 360°/n is multiplied by 1/2. Free geometry worksheets with visual aides, model problems, exploratory activities, practice problems, and an online component. To account for the conversion from radians to degrees, 1/n is multiplied by 360°/2. D 7.5 7.5 7.5 7.5 56.25 56. ![]() ![]() Since a triangle has 180°, to divide by 2n you must multiply the numerator by 2 as well. Which of the following gives the best reasoning for why the argument of the sine function, which is half of m ang BAC, is (360°)/(2n) ? ![]() Here, A would be the center of the circle, B and C would lie on the circle, and bar, which will be called a, one can use the formula a=2r sin((360°)/(2n)), where r is the radius of the circle and n is the number of sides of the inscribed polygon. Let triangle ABC be one of the triangles of the inscribed polygon referred to in the previous questions.
