From 102nd floorˏ an observer spot his car at an angle depression of 5 degree.If the observer is 1250 feet high; how far is his car from him?
looks like just
sin5° = 1250/hyp
where hyp is the hypotenuse you want
hyp = 1250/sin5°
= ...
sin5° = 1250/hyp
where hyp is the hypotenuse you want
hyp = 1250/sin5°
= ...
