<u>Answer:</u>
A plant needing full sun can be placed from a fence 4.63 ft high at a distance of 10.75 meter if the lowest angle of elevation of the sun in winter is 23° 18'.
<u>Explanation:</u>
The given figure shows the arrangement of sun, 4.63 ft high and plant needing full sun.
By using trigonometric result, tan θ = Opposite side/Adjacent side.
Substituting
tan(23° 18') = 4.63 ft/x
x = 4.63 ft/ tan(23° 18') = 10.75 m
So that a plant needing full sun can be placed from a fence 4.63 ft high at a distance of 10.75 meter.
