Question

the sum of all exterior and interior angles of a pentagon is

Answer 1

A pentagon has 5 sides.

-

Formula : Sum of interior angles = ( n - 2) x 180

Sum of interior angles = (5 - 2) x 180 = 540°

-

Formula : Sum of exterior angles = 360

Sum of exterior angles of a pentagon = 360°

-

Answer: Interior angles = 540°, external angles = 360°

Answer 2

Answer:

Sum of all interior angles of pentagon = 540°

Sum of all exterior angles of pentagon = 72*5 = 360°

Step-by-step explanation:

Sum of all exterior angles of polygons = (360/ no.of sides of the polygon) * 5

= (360/5) = 72

= 72*5 = 360°

Sum of all interior angles of polygons

= (2*no.of sides of polygon) - 4) *90.

= (2*5 - 4) *90

= (10-4) *90

= 5*90

= 540°
