The business owner should be told to angle a spotlight mounted on the roof at the angle of =39°
<h3>Calculation of angle</h3>
The distance of the flagpole from the building = 55ft
The building has the height of = 45ft
The flagpole has the height of = 25ft
The angle can be calculated using the formula;
Tan θ = opposite/adjacent
Where opposite= 45ft
adjacent = 55ft
Tan θ = 45/55 = 0.82
θ = Tan–¹0.82
θ = 39°

The problem ask to find the are of the shaded region of the circle which has a radius of 12cm. The are of the circle is computed as the formula of pie times the square of the radius so the are of the circle would be 452.389 cm2 and the area of the shaded region would be 150.796 cm2^2. I hope you are satisfied with my answer and feel free to ask for more
