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.

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
