Answer:
150°
Step-by-step explanation:
To find the sum of all the interior angles in a regular polygon, us this formula, where n is the number of sides: (n-2)*180
(12-2)=10
10*180=1800
Now we have the sum of all the angles. But we aren't done yet! We have to divide this value by the number of sides to find the measure of one angle.
So,
1800/12=
150
Hope this helps!
The area is (BK) times (AK or CK).
If you have no numbers given, it's not possible to find the length of BK, or the actual number that represents the area.
