The Earth is a watery place. But just how much water exists on, in, and above our planet? About 71 percent of the Earth's surface is water-covered, and the oceans<span> hold about 96.5 percent of all Earth's water. Water also exists in the air as </span>water vapor<span>, in </span>rivers<span> and </span>lakes<span>, in icecaps and </span>glaciers<span>, in the ground as soil moisture and in </span>aquifers<span>, and even in you and your dog.</span>
Answer:
The answer is 3438.16 i think
Step-by-step explanation:
We do not see a graph above
The length of the bottom beam =9.16 feet
<h3>What is Pythagoras theorem?</h3>
the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.
Given : Total length of arm = 3.4+3.4=6.8 ft
Applying Pythagoras in triangle on right side we have,
H²=P²+ B²
6.8²= P² + 4.8²
46.24= P² +23.04
P²= 23.2
P= 4.81 feet
Similarly, on the triangle on left side.
Again we have the base as 4.81 feet.
Now, the length of the bottom beam= 4.81*2
=9.16 feet
