it is normally all obtuse. * * * * * The sum of the interior angles of an n-gon is (n-2)*180 degrees. Since n = 18, the sum is 16*180 degrees. So each angle is 16*180/18 = 160 degrees.
The Answer is 15+17=32
69 + 18 = 67
sum of interior angles = (sides - 2) * 180 = 16 * 180 = 1800 + 1080 = 2880 degrees

They are 18 and -2.
The consecutive integers whose sum is 51 are 16, 17, and 18.
18 and -2
It is: 16+11-9 = 18
They are: 16+18 = 34
18 and -2
