Answer:
In the attachment.
Step-by-step explanation:
Rewrite 
as a 
. Then mark each set with different color and take the intersection of these.
<em><u>200x3=600</u></em>
<em><u>50x3=150</u></em>
<em><u></u></em>
<em><u></u></em>
<em><u>600+150=750</u></em>
<em><u></u></em>
<em><u>750</u></em>
One way to do this is use the fact that the exterior angles of all polygons add up to 360 degrees
So an exterior angle of a regular octagon = 360 / 8 = 45 degrees.
So each interior angle = 180 - 45 = 135 degrees
so total measure of all angles in octagon = 8 * 135 = 1080 degrees
