It is approx 36.6 ft.
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
10.08 feet approx.
The shadow:object ratio is 1:1 so the tree is 63 feet high.

The man is 5.96 feet tall and the lamp is 17.88 feet high.
It works out as 3.75 feet
4 is to 6 as 5 is to X. 4/6 = 5/X. X = 7.5 feet.
Earth casts the shadow.
Either the Moon casts its shadow on Earth, or the Earth casts its shadow on the Moon.
To solve this you need to put 5.3 over 8 to represent the first lamp post then you need to put x over 128, so you can find the height of the lamp post. The lamp post is 84 feet 8 inches.
(35/7)*4 = 20 Ft.
1. How high is a flagpole that casts a shadow of 45 ft at the same time a woman 5.5 ft tall casts a shadow 10 ft?
A tree casts a large shadow.
2
The height of the tree is in direct proportion to the pole and its shadow
