Sum of all three angles is 180 degrees. Two angles are 35 deg each, so their sum is 70 deg. The third angle is, therefore, 110 deg.
The sum of the internal angles of any regular polygon is (n - 2) x 180 degrees. Since a triacontakaihexagon has 36 sides, the sum of the internal angles of a triacontakaihexagon has a sum of internal angles of (36 - 2) x 180 = 6120 degrees.
The sum of the internal angles always equals 180o

Any quadrilateral may be split into two triangles; the sum of internal angles of any triangle is 180 degrees; so the sum of internal angles of a quadrilateral will then be the double of the sum of internal angles of a triangle: 180 x 2 = 360.
The sum of the internal angles of a pentagon is 540 degrees.

The sum of the internal angles of a heptagon is 900 degrees. This can be found be multiplying one angle, 128 and four sevenths, by 7.
The sum of the internal angles of any triangle is 180 degrees. Any rectangle has four 90 degree internal angles, totalling 360 degrees.
