The measures of two angles in a triangle are shown in the diagram. Which equation can be used to find the value of x?
The sum of the angles is 900 degrees - and the polygon does not need to be convex.

The sum of exterior angles, of any polygon - convex or concave, and whatever the number of sides - is 360 degrees or 2*pi radians.
Use the formula (n - 2)180 to find the sum of the measures of the interior angles of any regular convex polygon, where n is the number of sides. (n - 2)180 = (18 - 2)180 = (16)180 = 2880
(22-2)*180 degrees = 20*180 deg = 3600 deg.
find the sum of the measures of the interior angles of 13-gon.
The interior angles of a 14 sided polygon add up to 2160 degrees
If it is convex (i.e. no angles bend backwards), the four internal angles add up to 360°
To find the sum of the interior angles of a convex 12-sided polygon, you use the formula (n-2)180 n being the number of sides Therefore, (12-2)180 = 10(180) = 1800 degrees So the sum is 1800 degrees I believe this is right, but please correct me if I am wrong.
