You can put this solution on YOUR website! a pentagon of 5 sides has three angles which are each 140 degrees,the other two interior angles are equal.calculate the size of one of these angles
--------------
a pentagon of 5 sides - all pentagons have 5 sides
----------
The sum of the internal angles = (n-2)*180 degs
n = 5
