Question

sum of the angle of a polygon is 4320 then what is the sum of the angle of a polygon with one side less than the polygon​

Answer 1

Step-by-step explanation:

sum of angles of a n sided polygon is (n-2)×180°

here given that sum of angles is 4320

4320 = (n-2)×180

(n-2) = 4320/180 = 24

n = 26

now we need to find the sum of angles of a polygon with 25 sides

(25-2)×180° = 23×180° = 4140°
