Using trigonometric ratio, the distance of the bus top to the man is 38 feet.
A right angle triangle has one of its angles as 90 degrees. The sides and angles can be found using trigonometric ratios.
Therefore, the opposite side of the triangle is 140 feet.
The distance of the man to the bus top is the adjacent side of the triangle formed.
tan 75 = opposite / adjacent
tan 75 = 140 / a
a = 140 / tan 75
a = 140 / 3.73205080757
a = 37.5335120643
a = 38 feet
Therefore, the distance from the man to the bus top is 38 ft.
