You need more info, probably an angle of elevation or something like that.
It may be 14ft tall.
It works out as 12 feet and 4 inches in height
We can solve this problem using a ratio. Since a 6 foot man casts a 4 foot shadow we can write this ratio as 6:4. If we reduce this ratio we get 3:2. Now we're stating that for every 3 feet of height, the shadow cast will be 2 feet.Now we can work our problem out using a small table:3 feet of flag pole = 2 feet of shadow6 feet of flag pole = 4 feet of shadow9 feet of flag pole = 6 feet of shadow12 feet of flag pole = 8 feet of shadow15 feet of flag pole = 10 feet of shadow18 feet of flag pole = 12 feet of shadowTherefore an 18 foot flag pole will cast a 12 foot shadow at the same time that a 6 foot man casts a 4 foot shadow.
The height of the tree is in direct proportion to the pole and its shadow
The tree is 25 feet tall. A 5 foot pole cast a 2 foot shadow. This means that the sun angle causes the shadow to be 2/5 the length of the object casting it. The tree's shadow is 10 feet tall. Multiply 10 feet by 5/2 (inverting the fraction because we're going the other way) and we get 25 feet.
Required angle has a tangent of 7.6/6.1 ie 1.249. This is 51.25 degrees.
15 feet high
To determine the height of the tree based on the shadow length, we can use the concept of similar triangles. If the tree casts a shadow of 1 foot while a 1-foot pole also casts a shadow of 1 foot, then the height of the tree is the same as the height of the pole. Thus, the tree is also 1 foot tall.

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.

Assuming the two poles are parallel . Then use Similar Triangles. 27/18 is to 63/x Equating 27/18 = 63/x Algebraically rearrange x = (63/27) X 18 Cancel down (reduce) by '9' x = (63/3) X 2 Cancel down (reduce by '3') x = (21/1) X 2 x = 42/1 = 42 ft. (Which is the length of the shadow created by the 63 ft. pole).
The height of the tree is in direct proportion to the pole and its shadow
