Draw right triangle and high marked wid h, lenght of shadow marked wit s.
Angle off 66° betwen horizontal line and sloping line mark with á.
Then:
tan(á)=h/s
h=s*tan(á)
h=20*tan(66°)=20*2.246037=44.92074ft
In My answer á mean Greek letter Alpha
If the height of the building is 250 feet,the angle of the shadow is 49 degress, what is the distance from the top of a building to the tip of its shadow?
