an aerial photographer who photographed real estate properties has determined that the best photo was taken at the height of approximately 471 feet in a distance of 859 feet from the building what is the angle of depression from the plane to the building

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.

this cant be answered without the graph. you may need to add it.

the answer is  

d.

121π mi^2

hope you got it chief
