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

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

so then 180(5-2)?

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

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.
