Find the measure of an interior angle of a regular polygon with 15 sides. round to the nearest tenth if necessary.

156 dergrees

Step-by-step explanation:

Each triangle has an angle sum of 180 degrees, so the sum of the interior angles of the 15 must be 13 × 180 = 2340 degrees. Since the 15 is regular, this total is shared equally among the 15 interior angles. Each interior angle must have a measure of 2340 ÷ 15 = 156 degrees.

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.
