Hey the solution to your question is (5,10).
8,748 is the answer because multiple all the number and get 8,748
Area squares is the side*side, or



So, each side equals 5.
Answer: I think its d if im wrong im so sorry
Answer:
x=6/cos(72) is the exact answer.
.
Step-by-step explanation:
Sine

Soh Cah Toa is an abbreviation used to help remember the trigonometric ratios.
We see we have the angle measurement 72 degrees given at the bottom. I'm going to label my sides with respect to that angle.
The hypotenuse is x.
The adjacent is 6.
We don't have anything about the opposite side but we don't need it to find x.
So anyways we have this:
The hypotenuse is x and
the adjacent is 6.
If you look at the ratios we want to use cosine.

or

We are going to cross multiply.
x cos(72)=1 (6)
cos(72) * x=6
Now we are going to divide both sides by cos(72) giving us:
x=6/cos(72)
x=6/cos(72) is the exact answer.
Let's put it into our calculator now:
