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.

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.
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 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)
A tree casts a shadow that is 21 feet long at the same time as a fence post casts a shadow that is 6 feet long The fence post is 4 feet tall What is the height of the tree?
Ratio of object to its shadow is the same. So if T is the height of the tree, then T/21 = 4/6 So T = 21*4/6 = 84/6 = 14 feet
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 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 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.
If a tree 10 feet tall casts a shadow 5 feet long how long is the shadow cast by a pole 12 feet tall?
6 feet

A tree is 18 feet tall and casts a shadow 6 feet long A nearby sign casts a 3 foot shadow What is the height of the sign?
A 1 foot shadow I think.
How tall is a tree that casts a 30 ft shadow at the same time an 18 ft pole casts a shadow that is 6 feet long?
It is 90 feet in height
How Elijah is 5'9 tall and casts a 4 foot shadow. He is standing near a tree that casts a 24 foot shadow. How tall is the tree?
The tree is 34.5 feet tall because tangent ratio of 34.5/24 = 5.75/4
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.

A vertical pole 5 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?
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.
How tall is a tree that casts a 25 foot shadow at the same time a 9 foot light pole casts a 15 foot shadow?
