Here is the answer OwO:
A 12-foot flagpole casts a nine-foot shadow. The measure from the top of the shadow to the top of the flag pole is 15.
Here is the explanation/work OwO:
Switch sides.
c^2=12^2+9^2
12^2=144
c^2=144+9^2
9^2=81
c^2=144+81
Add the numbers: 144 + 81 = 225
c^2=225
For x^2 = f(a) the solution is √f(a)
c = 15
Therefore, your answer will be 15.
