lgbasallote · Answer

use $$\large 180(n-2)$$ a pentagon has 5 sides

anonymous · Answer

okay i thought so

anonymous · Answer

so then 180(5-2)?

anonymous · Answer

should be [180(5-2)]/5. 180(n-2) is total interior angle, so to get the value of each angle just divide it by n.

lgbasallote · Answer

yes @LovelyMegan

anonymous · Answer

@lgbasallote you have to divide it by n to get the value for each angle.

ok im not getting any of the asnwer's

HEYYYYYYYY
i got it 
its 108 right?
plz tell me im right :)

anonymous · Answer

Formula to find the sum of all interior angles = 180(n-2) where n is the number of sides.

First, use this formula to find the sum of all interior angles. In this case, it's a pentagon, so there will be  5 sides, whereby n=5. so sum of interior angles=180(5-2)=540. since it's a regular pentagon, all sides are of the same length, therefore all interior angles are of the same value. so to find the value for each angle, just take 540/5 which is 108 degrees.
