Answer: 
Step-by-step explanation:
For this exercise you need to use the following formula for calculate the area of regular polygon:
Where is "s" the length of any side, "n" is the number of sides.
Int this case you know that it is regular pentagon, which means that it has five sides. Then you can identify that the values of "n" and "s":
Therefore, substituitng values into the formula, you get that the area f the pentagon is:
Hello,

(y-5)=2(x-0)
Answer:
In the complex number 4 + 2i, 4 is the <em>real </em>part. In the complex number 4 + 2i, 2 is the <em>imaginary </em>part.
Step-by-step explanation:
The two parts of the complex number are called the <em>real</em> part and the <em>imaginary</em> part. The imaginary part is identified by its multiplier of <em>i</em>.
In the given number, the 2 is multiplied by i, so 2 is the imaginary part. The other part, 4, is the real part.
Answer:
30 ft
Step-by-step explanation:
We can use ratios
3 6
------ = ------------
15 x
Using cross products
3x = 6*15
Divide each side by 3
3x/3 = 6*15/3
x = 30
