Question

How many degrees are in each interior angle of a regular pentagon?
50
72
108
120

Answer 1

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

Answer 2

okay i thought so

Answer 3

so then 180(5-2)?

Answer 4

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.

Answer 5

yes @LovelyMegan

Answer 6

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

Answer 7

ok im not getting any of the asnwer's

Answer 8

answer's

Answer 9

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

Answer 10

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.

Answer 11

@LovelyMegan yes you're right. :)
