The length of the ladder is 5.3 meter if the base of a ladder is placed 2.8 m away from a tree that is 4.5 m tall. The end of the ladder touches the top of the tree.
<h3>What is a right-angle triangle?</h3>It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.
As per the picture attached, the triangle is a right angle triangle:
Let's assume the length of the ladder is x meter
From the Pythagoras theorem:
x = √(2.8²+4.5²)
x = √(7.84+20.25)
x = 5.3 m
Thus, the length of the ladder is 5.3 meter if the base of a ladder is placed 2.8 m away from a tree that is 4.5 m tall. The end of the ladder touches the top of the tree.

Answer:
<em>The volume of the cube is </em> <em>cu in.</em>
Step-by-step explanation:
<u>The Volume of a Cube</u>
Let's have a cube of side length a. The volume of the cube is:
The cube of the image has a side length of
Simplifying the expression of the base by converting the negative exponent in the numerator to the denominator:
Now find the volume:
Applying the exponents:
The volume of the cube is cu in.
