The answer to this tautological question is: 10.
1/10 , 3/10 , 6/10 . Their sum is (1+3+6)/10 = 10/10 = 1
They add up to 17
10 exterior angles add up to 360 degrees 10 interior angles add up to 1440 degrees Its perimeter is the sum of its 10 sides
Any number you can add up to get the sum
Two-digit prime numbers whose digits add up to 10 are:193773
When you add up the answer you get in the end is called the 'sum'.
If half of the sum is 90 then the full sum must be 180. The three consecutive multiples of 10 which add up to 180 are 50, 60 and 70.
The sum of the angles of a triangle MUST add up to 180o.
The 10 interior angles of a decagon add up to 1440 degrees
A 10 sided decagon has interior angles that add up to 1440 degrees
Exterior angles add up to 360 degrees Interior angles add up to 1440 degrees
