An aerial photographer who photographs real estate properties has determined that the best photo is taken at a height of approximately 483 ft and a distance of 858 ft from the building. What is the angle of depression from the plane to the building?

x = distance from the building = 837ft

y = height = -483ft (The building is DOWN from the plane.)

θ = angle of depression = to be determined

tan θ = y/x

tan θ = -0.577060932

θ = arctan (-0.577060932)

θ = -29.98756509° ≈ -30° (The building is DOWN from the plane.)

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
