The multiplication fact 1 x 85 = 85 with 1 and 85 adds to 86; The multiplication fact 2 x 84 = 168 with 2 and 84 adds to- 86; etc. But I don't quite think that is what you mean; I think you mean what are the factor pairs of 86: 1 x 86 & 2 x 43.
The sum of the interior angles is, and here's a wild guess, 1620!
Iy adds up to 360 degrees
Because the sum of their digits add up to 16 which finally adds up to 7
If the digit sum of a number adds up to 9 then it is divisible by 9.
The polygon will have 42 sides
The sum of all the angles in a triangle always adds up to 180 degrees.
227
No. The only digit of 2 is ' 2 '. It adds up to 2.
its sum of digits adds up to something divisible by 3, so, yes, it is.
There is a formula for the total of the interior angles. A triangle (3 sides) adds up to 180°. A quadrilateral adds up to 360°. A pentagon adds up to 540° and a hexagon adds up to 720°. Notice that for each additional side, the sum of the interior angles increases by 180°. The general formula for an 'n' sided polygon is: (n-2) * 180° So (6-2) * 180° = 4 * 180° = 720° (like I said before)
