I am soo late but Happy Birthday!!

nvm!

thx!

I don't think that that is correct. Thanks though! Can someone else help?

And how can triangle ABC be a 30-60-90 triangle when angle A is 36 degrees?

How did you prove that? Also, I would like help for the whole thing, as I am really confused.

Are there any steps?

It is actually 66, but thank you!

16.71 is still wrong?

Steps please?

Hi Pangolin14. Thank you! Did you try to attach an image? It says Not Available?

To solve this problem, we can use some basic maths. The mean of a data set is derived from the sum of the data numbers over the number of data numbers. If you need some more help, feel free to ask!

Hello Guest,

To solve this problem, we can first use the distance formula. Find the length of the sides first.

(Hint: If you don't know the distance formula, it is: \(d=\sqrt{(x2-x1)+(y2-y1)}\)

Then, using the side lengths, you can apply the formula of b*h where b is the base, and h is the height to the rectangle and find the area. Please let me know if you need more help!

Sorry, I should have made it clear in the question. I would like some specific steps so that I know how to do these problems in the future. Thank you!

Yes, I do. Thank you!

Hi Nacirema, 

I had this same problem, and I needed it in fraction form as well. I am assuming that you need it in fractional/radical form because you use AoPS. You will find the radical answer here:https://web2.0calc.com/questions/can-anyone-solve-this_6.

Hope this helps!
