Problema Solution

Three angles are 105.5. If the sum of angles in a polygon is 2520. Find the remaining angles

Answer provided by our tutors

For a polygon with n sides and n angles, the sum of the measures of all the interior angles equals (n-2)180 degrees.

For a polygon whose angles add up to 2520 degrees,

We know the measure of 3 of the 16 angles. We have to find the measure of

16-3=13 angles.

If 3 of the angles measured 105.5 degrees, and the 13 remaining angles measure x degrees,
