SOLUTION:

We are to find the measure of an interior angle of a regular decagon.

A decagon is a plane figure with ten straight sides and angles.

To find the sum of interior angles in a decagon;

(n - 2) x 180 (where n = 10)

(10 - 2) x 180

= 8 x 180

= 1440 degrees

The measure of an interior angle of a regular decagon is;

1440 / 10

144 degrees
