The sum of the numbers 1 to 39 = 39 x 40 ÷ 2 = 780 The sum of the numbers 1 to 60 = 60 x 61 ÷ 2 = 1830 Therefore the sum of the numbers 40 to 60 = 1830 - 780 = 1050
The interior angles of a 39 sided polygon add up to (39-2)*180 = 6660 degrees
The interior angles of a 39 sided polygon add up to (39-2)*180 = 6660 degrees
The interior angles of a 39 sided polygon add up to (39-2)*180 = 6660 degrees
25 + 14 = 39 25 - 14 = 11
It is: 1225+39 = 1264
