Answer:
720
Step-by-step explanation:
The sum of the interior angle is determined by the number of side a polygon has.
The sum of the interior angle of any triangle is 180
The sum of the interior angle of any square is 360
The sum of the interior angle of any pentagon is 540
The sum of the interior angle of any hexagon is 720
So the answer is 720.
Note that the angle increases by 180 for every increase in the number of sides of the polygon.
