apolice helicopter hovering in a fixed position at an altitude of 500m moved its spotlight through an angle of depression of 57◦ onto a lost child. the pilot sighted the rescue team at an angle of depression of 31◦. if the terrain was level, how far, to the nearest metre, was the rescue team from the child?.
