Let me tell you the process so that you get to the answer
Remember first that the area of a regular polygon with x sides has each of them a length which can be represented by y
<span>A = 1/4 * xy^2 * Cot(180/x) </span>
<span>The purpose is to solve for y, so we get </span>
<span>y^2 = 4A/(xCot(180/x)) </span>
<span>y = √(4A/(xCot(180/x)))
The thing we need to change is A in the previous formula and with that we can use the equaation to be a constant. This could be represented by Z
</span><span>Z = √(4/(xCot(180/x)))
so
</span><span>Y = Z√A
</span><span>If we increase area by a factor s, y increases by a factor of √x.
</span>So if you want to know the triple then you need to increase it by <span> √3 </span> <span> </span>
Answer:
85%
Step-by-step explanation:
We have 30, 35, and 20.
Your question is asking what the total percent is. Since these percents are all on only a single item, we can just add them together.
30 + 30 = 60
60 + 25 = 85
There we go! 85%

Answer
Find out the percent error in Annie's estimate .
To prove
Formula

As error = approx value - exact value
As given
Annie estimates that the height of a bookcase is 78.25 in.
The actual height is 75.50 in.
approx value = 78.25 in.
actual value = 75.50 in.
error = 78 .25 - 75 .50
= 2.75
put in the formula


Percentage error = 3.64 % (approx)
Therefore the Percentage error be 3.64 % (approx).
Answer:
angles that are all equal and sides that all have the same length
