It depends on the angle of the sun. The height of the tree is equal to the lenght of its shadow times the cotangent (or divided by the tangent) of the sun's angle above the horizon.

When a 5 foot vertical pole casts a 3 foot 4 inch shadow and an oak tree casts a 20 foot shadow then what is the height of the tree?
Assuming that you are not using angles, but only ratios I have the following:Your answer is 30 ftCalculations:5 ft : 3f & 4 in (40in)20 * 12 = 240 in240 / 40 = 66 * 5 = 30 ft
A 20 inch post casts a shadow 16 inches long how tall is a post that casts a shadow 12 inches long?
20/16 = h/12;Cross multiply: 16 x h = 20 x 12h = 20 x 12/16 = 240/16 = 15 in
How long is the shadow of a 5 feet 4 inch person if a 8 foot cast a 3 foot shadow?

If a 30 foot flagpole casts a 12 foot shadow how tall is a mailbox casting a 18 inch shadow?
First find the angle of elevation by using the tangent ratio formula:tangent = opposite (the flagpole)/adjacent (the shadow)tangent = 30/12 = 68.19859051 degreesThen rearrange the formula to find the height of the mailbox:height of mailbox = 18*tangent 68.19859051 = 44.99999......Therefore: height of mailbox = 45 inches to the nearest inch.Or,Since we have two similar right triangles whose legs are the 30 feet flagpole and its 12 feet shadow, the length x of mailbox and its 18 inches shadow, we have:18 in/x = 12 ft/30 ft (cross multiply)(12)(x) = (30)(18 in)12x = 540 in (divide by 12 to both sides)x = 45 in
