A person whose eye level is 16 feet above the ground is looking at a building. The angle of elevation to the top of the building is 22∘ and the angle of depression to the bottom of the building is 17∘. What is the height (in feet) of the building? Round your answer to the nearest foot.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
