each interior angle of a regular polygon is 120 degrees greator than each exterior angle.how many sides are there in the polygon
Choose the correct choice from the following choices
A) 6  B) 8  C) 12  D) 16  E) 18
Interior angle = 180 - (360/n)   Exterior angle = (360/n)   Given: IA = 120 + EA   =&gt; 180 - (360/n) = 120 + (360/n)   =&gt; n = 12   ANSWER:12
