Question

a) determine the measure of angle x in the shape below. assume c is the center of the circle. (4 marks)

recall: inscribed angle theorem: the measure of the central angle is twice the measure of an inscribed angle. solve for x using 2x = y.

the measure of angle x is ______.

b) the regular polygon below has 15 equal sides. find the measure of angle x. (4 marks)

recall: sum of interior angles of polygons formula: (n - 2) * 180 degrees, where n represents the number of sides.

the measure of angle x is ______.
