<span>Let the height of tree be denoted as AB and the shadow cast by the tree be BE. ABE is the triangle formed the tree, rays and the ground. Let the height of the person be CD and the length of his shadow be DE. CDE is the triangle formed by the person, rays and the ground.
We have two triangles. Both the person and the tree stand vertically over the horizontal ground, therefore they make 90 degrees with the ground. The angle formed at the ground is the same for the both the triangles. Therefore, by AA similarity the two triangles are similar.
We know that if two triangles are similar, then their sides are proportional.
Therefore,
AB/CD =BE/DE
AB/6 = 143/11
AB= (143/11) *6
AB = 78 ft.</span>
The answer is 189,729
If to be rounded answer would be 190,000 I would say best estimate would be 180,000
Yes. For example, the shape I will use is the circle.
No matter how you rotate the circle, it will always look the same. If you reflect the circle over any drawen line in which it passes through the middle, the two halves created would be congruent.

130 =
2 * 5 * 13
The prime factors are 2, 5, and 13.
No prime factors are used more than once.
The only exponents to write might be the understood 1.
130 = 2^1 * 5^1 * 13^1
Instance variables are often called "fields" to help distinguish them from other variables you might use.
<h3>What are Instance variables?</h3>
Instance variables are defined within a class but outside of any method, constructor, or block.
Some key points related to Instance variables are-
- When heap space is allocated to an object, a slot is created for every instance variable value.
- Whenever an object is created with keyword 'new,' instance variables are created, and they are destroyed whenever the object is destroyed.
- Instance variables store values that need to be referenced by multiple methods, constructors, or blocks, as well as vital components of an entity's state which must be available throughout the class.
- Before or after use, instance variables could be declared just at class level.
- Variables, for example, can be given access modifiers.
- Only those methods, constructors, and blocks in the class have access to the instance variables.
