If billboard is 18 ft high and cast a 24 ft shadow at the same time a flagpole next to a billboard cast a 60 ft shadow how high is the flagpole?

They both have the same tangent ratio so let the flagpole be x:
x/60 = 18/24
Multiply both sides by 60:
x = 1080/24
x = 45 feet

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.
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.
How high is a tree that casts a 37 ft shadow at the same time a 4foot pole casts a 12 foot shadow?
It works out as 12 feet and 4 inches in height
If a man that is 6 feet tall is standing near a street light that is ten feet high If the shadow that is cast extends twenty feet away from the light how far away is the man?
The man is 9 feet away from the street light.
How high is a tree that casts a 24 ft shadow at the same time a 12 ft post casts a shadow which is 12 ft long?
As the sun is far enough away, the rays of light are effectively parallel. This produces similar triangles with the ratio of sides the same in each case. As the shadow of the post is 12 ft and the shadow of the tree is 24 ft, the sides of the triangle of the tree are double that of the post. Assuming the post is parallel to the tree, the tree's height is twice the height of the post → tree = 12 ft × 2 = 24ft high.
How tall is a billboard that casts a 45 ft shadow at the same time that a 5.5 woman casta a 10ft shadow?
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?
When the shadow of a flagpole is 31.2m long a 1.6m fencepost casts a shadow 2.6m long how tall is the flagpole?
First, find the ratio of fencepost-height : shadow which is 1.6 : 2.6 . This can also be written as a fraction, 1.6/2.6 . Then, multiply the flagpole's shadow by this ratio: 31.2 x 1.6/2.6 = 19.2 The flagpole is 19.2m high. The trigonometry way: On the imaginary right angled triangle formed by the fencepost and its shadow, let the angle at which the hypotenuse meets the ground = θ sinθ = 1.6/2.6 sinθ = /31.2 x/31.2 = 1.6/2.6 2.6x = 31.2 * 1.6 = 49.92 x = 19.2 The flagpole is 19.2m high.
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?
If Blake is standing next to a flagpole that is 65 feet high Blake who is 5 feet 10 inches tall is casting a shadow that is 20 feet 6 inches long Approximately how long is the shadow of the flagpole?
Just over 228 feet.
what is the angle of elevation of the sun when a flagpole 22.5 m high casts a shadow 32.4 m long?
If we assume the the flagpole makes a 90 degree angle with the ground, then the angle of elevator for the sun is 34.778°
A 10-meter high flagpole casts a shadow 6 meters long How long is the shadow of a nearby bush that is 3 meters tall?
1.8 meters. The ratio of object to shadow is 10:6. Therefore if the object is 3, the shadow is 1.8 ( 6/10x3).
How high is a tree that cast a 25 ft shadow at the same time a 9 ft post cast a shadow which is 4 ft long?
56.25 feet
A pole 15 feet high cast a shadow 5 feet long a 6 foot man standing nearby would cast a shadow?
Divisibles, the 6 foot man would cast a shadow 2 feet long.
When a shed 9.5 in high casts a shadow 6.2 m long how long is a shadow cast by a person 2.1 m?
3.4
Blake is standing next to a flagpole that is 65 feet high Blake who is 5 feet 10 inches tall is casting a shadow that is 20 feet 6 inches long Approximately how long is the shadow of the flagpole?
Let the length of the shadow be x and change all the feet into inches to avoid fractions. 780/x = 70/246 Multiply both sides by x: 780 = 70x/246 Multiply both sides by 246: 191880 = 70x Divide both sides by 70: x = 2741.142857 inches and when divided by 12 = 228.4285571 feet So the length of the shadow is about 228 feet.
Why do not things flying high aeroplane cast their shadows?
Objects do cast shadows at higher altitudes in the same way they do on the ground; however, the shadow may not be visible due to the lack of contrast against the sky. Additionally, the position of the sun in the sky and the angle at which light is hitting the object can also affect the visibility of the shadow.
A tree cast a 24-foot shadow at the same time a fence post 5 feet high cast a 4-foot shadow how tall is the tree?
It works out as 30 feet in height
