<PRE><B>Question 721189</B>
1- CALCULATE THE SIZE OF EXTERIOR ANGLES OF A REGULAR POLYGON WHICH HAS INTERIOR ANGLES OF:
a) 150 degrees
Subtract from 180
180 - 150 = 30 degrees
-----------------
b) 175 degrees
c) 162 degrees
d) 174 degrees

2- the size of the exterior angle of a regular polygon is 12 degrees. how many sides does this polygon have?
The sum of the exterior angles = 360
360/12 = 30 sides
