Assuming that you are not using angles, but only ratios I have the following:
Your answer is 30 ft
Calculations:
5 ft : 3f & 4 in (40in)
20 * 12 = 240 in
240 / 40 = 6
6 * 5 = 30 ft

A vertical yardstick casts a 1 foot shadow and the same tree nearby casts a 15 foot shadow How tall is the tree?
That depends on the height of the yardstick whose height has not been given.
What is the length of the shadow cast by a 63 foot high pole if a 27 foot high pole casts an 18 foot shadow?
If a 27 ft tall pole casts an 18 foot shadow, a 63 ft tall pole casts an x foot shadow.Put 27/18 and 63/x.Cross multiply, get 27x=1134Divide by 27 on both sides, a 63 foot tall pole casts a 42 foot long shadow.
How far is it from the top of the flag pole to the tip of the shadow if the flag pole that is 18 feet tall casts a 24 foot shadow?
Using Pythagoras' theorem it is 30 feet
How tall is the pole if the pole casts a 24-foot shadow and a 3 and one half foot tall boy casts a 6-foot shadow while standing beside the pole?
Answer is 14 feet
At a certain time of day the angle of elevation of the sun is 30 degree A tree has a shadow that is 25 feet long Find the height of the tree to the nearest foot?
Tan60= 25/Height. Height = 25/Tan60 = 14.43

At a certain time of day a tree casts a 9 foot shadow at the same time that a person 6 feet tall casts a 4 foot shadow What is the height of the tree?
If the shadow of a 6-ft person is 4-ft long, then in this place at this moment, all shadowsare 2/3 the length of the vertical object that casts them.The 9-ft shadow therefore 2/3 the height of the tree. The height is (9)/(2/3) = (9 x 3/2) = 13.5-ft.-----------------------------------------(9/4)*6=13.5 ft.
How high is a tree that casts a 37 ft shadow at the same time a 4foot pole casts a 12 foot shadow?
It works out as 12 feet and 4 inches in height
A 3 foot pole casts a 6 foot shadow A 4 foot pole casts an 8 foot shadow Use a linear equation to predict the length of a shadow cast by a 6 foot pole?
Shadow lengths are proportional to the heights of objects casting the shadows. Therefore, calling the shadow length l, the height h, and the proportionality constant k, l = kh. (The intercept is 0 because an object with no height casts no shadow.) Therefore, in this instance k = l/h = 6/3 or 8/4 = 2. then l(6) = 2 X 6 = 12 feet.

How tall is a boy that casts a 4 ft shadow?
The height of a boy that casts a 4 foot long shadow depends on the angle of the sun. A tangent can be used to calculate his height if we know the angle of the sun using the equation: Height = shadow length x tangent of the angle of the sun. Using a calculator, it is easy to get the value of the tangent for any angle and then complete the equation.
