Best Answer

You only know that all ten interior angles of a 10-sided figure add up to 1,440 degrees.

IF the 10-sided figure happens to be REGULAR, then each of them is 144 degrees.

Decagon is 10 sided figure. Internal angles of 10 sided figure is (2 x 10 - 4) right angles = 16 x 90 degrees, hence one angle is (16 x 90)/10 = 16 x 9 = 144 degrees

Its interior angles are: (10-2)*180 = 1440 degrees If its a regular 10 sided polygon then each interior angle is: 1440/10 = 144 degrees

A regular 10 sided decagon has 10 interior angles that add up to 1440 degrees and each interior angle is 1440/10 = 144 degrees

A 10 sided decagon has interior angles that add up to 1440 degrees

Exterior = 36 degrees Interior = 144 degrees

The exterior angle is given by 360 / 10 = 36 degrees. The interior angle is given by 180 - the interior angle, ie 180 - 36 = 144 degrees.

It is: 144 degrees

144 of them.
