Answer:
540°
Step-by-step explanation:
The sum of all the interior angles in a pentagon with 5 sides is 540°.
Using the formula for finding the sum of interior angles of polygons
(n-2)×180
Where n is no. Of sides
For pentagon (5 sides) it will be
=(5-2)×180
=(3)×180
=540
So angles of a pentagon add up to 540°
