The sum of the interior angles of a 15-gon is (15-2)x180 degree which is 13x180 degrees or 2340 degrees.

The radius of the sector with an angle of 27 degrees and arc of 12cm is: 25.46 cm

The measure of a single internal angle of any regular polygon is equal to 180 (n - 2) / n. Therefore, an internal angle of a regular icosikaiheptagon (27-sided polygon) is equal to 13.3 recurring, or 13 and one third, degrees. It thereby follows that a measure of the external angle of the same polygon is equal to 180 - 13 and one third = 166.6 recurring, or 166 and two thirds, degrees.

Providing that it's a regular 27 sided polygon then the interior angles add up to 4500 degrees and each interior measures 166o40'0''

Since you are asked to find the complement you need to find 90 degrees total. An angle of 27 degrees complements an angle of 63 degrees. Your answer is 27 degrees.

The answer is still 108 degrees, if you call the angle, "360 degrees". But, lets say your angle is 90 degrees, then of course you would multiply 90 degrees by .30 (again, 30% changed to a decimal), and you would get 27.00, or 27 degrees, and that would be 30% of an angle measure, 90 degrees. I hope that helps some, and if not, I fear that I am not understanding the question fully and maybe message me back once again, asking the question again, but more in depth.

The angles of a triangle must add to a total of 180 degrees, so if you have 27 and 58 as two of your angle measurements the rest is easy. 27+58 = 85 180-85 = 95 Your third angle will be 95 degrees.
