THE MEASURE OF EACH OF THE SIX EQUAL ANGLES ARE :
* An octagon has eight sides.
* Two angles are equal and measure 120 degrees.
* Let the remaining equal angles be x.
* Sum of Interior angles of an octagon =(2N-4)90
=1080.
(where N is the number of sides)
Thus,
120+120+6(equal angle)=1080
240+6x=1080
6x=1080-240
6x=840
x=840/6
x=140.
Therefore the measure of each equal angle is 140 degrees.
