Taylor is looking out a window her eyes are 900 feet above ground she sees a car outside the window that is 1550 feet from her approximately how far is the car from the entrance yo the building

Use the pythagoras theorem:-
The hypotenuse = 1550 feet so

1550^2 = x^2 +  900^2   where x is the distance of the car from the building.

x^2 = 1550^2 - 900^2 =  1592500

x = sqrt 1592500 =  1262 ft  to nearest ft.
