The length of the shadow at any moment is proportional to the height of the object casting the shadow. call the unknown height of the tree h, then, h/7 = 0.9/2, or
h = 7(0.9)/2 = 3 m, to the justified number of siginifcant digits, or 3.15 m if the single digit numbers given are all considered to be exact.

A person 122 cm tall casts a 37 cm shadow at the same time a tree casts a 148 cm shadow. How tall is the tree?
488 cm
A tree casts a shadow that is 20 feet long Frank is 6 feet tall and while standing next to the tree he casts a shadow that is 4 feet long How tall is the tree?
The ratios are in the same proportion, so all you need to really figure out is what is in the same ratio to 20 as 6 is to 4.
If a tree casts a 22 foot shadow at the same time a 6 foot tall person casts a 4 foot shadow how tall is the tree?
The tree is 33 feet tall. Use ratios to solve this equation. 6/4 = n/22 6 x 22 = 4n 4n = 132 n = 33
A building that is 150 ft tall casts a shadow of 20 feet long at the sam time a tree casts a shadow of 2 ft how tall is the tree?
h = height of tree 150 / 20 = h / 2 h = (150/20) X 2 h = ? (you figure it out)
If a tree is 12 feet tall and has a 16 ft shadow how tall is a tree that casts a 20 ft shadow?
Assuming the shadows are measured at the same time of day and that the trees are on level ground, the tree with a 20-foot shadow is a quarter longer than the tree with a 16-foot shadow. Adding a quarter of the height to 12 feet makes it 15 feet tall. Alternatively use the tangent ratio which will be opposite (height of 1st tree) over adjacent (its shadow) and multiply it by the adjacent of the 2nd tree: (12/16)*20 = 15 feet tall.

In sunlight a vertical stick 9 ft tall casts a shadow 7 ft long. At the same time a nearby tree casts a shadow 28 ft long. How tall is the tree Round to the nearest tenth.?
The tree is 36.0 feet tall using the tangent ratio.
In the sunlight a vertical stick 9 ft tall casts a shadow 7 feet long a nearby tree casts a shadow 28 ft long how tall is the tree round to the nearest tenth?
36.0 feet
If a tree 17 feet tall casts a shadow 12 feet long how high is a building that casts a shadow 19 feet long?
To cast a 19 foot shadow the building would have to be 26.91 feet tall. Each foot of building/tree casts 8.47 inches of shadow.
A vertical pole five feet long casts a shadow of 2 feet if at the same time a nearby tree casts a shadow of 10 feet how tall is the tree?
25 feet tall
If a tree casts a shadow of fifteen meters long how tall is the tree?
Not enough information has been given to solve this problem such as: What is the angle of elevation?
A 6ft tall post cast a shadow on the ground that is 4.5ft long a tree cast a shadow 15ft long How tall is the tree?
Let x= height of the tree By ratio and proportion: 6ft/4.5ft = x/15ft 4.5ft x = 6ft (15ft) x= 20ft.
When a tree cast a 20 foot shadow a man 6 feet tall casts a 3 foot shadow how tall is the tree?
The man is twice as high as his shadow. Therefore, the tree must also be twice as high as its shadow, which would make the tree 40 feet tall.
