If you have a 20 dollar gold coin, it is worth a lot, at least $1500. You need to know what year the coin is from.
It depends on the condition. An average about uncirculated example runs from $30-50 and a truly uncirculated coin can sell for around $100 or so. Well worn coins are worth about $20 or so, mostly for their silver content. The Stone Mountain Half dollar is one of the more common early commemoratives but is incredibly popular.
well all triangles are 160 degrees or was it 180??? anyways if you have a problem like this: 20, 56, x to find the value of x you do 20 + 56 = 76 so 160 or 180 - 76= 84 or 104 is the value of x. hope this helps if not sorry for confusing you

The area of a circle = pi*radius^2 =~3.14 x 20^2 =3.14 x 400 =1256.64 m 3.14 is a rounded value for pi. You can find a more exact value, and online tools to allow you to multiply by pi through a search engine.
The area is given by xy and the perimter is given by 2x + 2y, where x is the side length and y is the height. So we have two equations: A = xy, P = 2x + 2y. Because the square and the rectangle have the same perimeter, P will be a constant, say 40. We can simplify this to the equivalent 20 = x + y by dividing both sides by 2. We can then rearrange it to y = 20 - x or vice versa for x and y. By substituting this into the first equation, we get A = x(20 - x) = 20x - x2. By using differentiation, we can find the x value for which A is maximum: A' = 20 - 2x Set A' to 0 (we know this will be a maximum because the x2 coefficient is negative): 0 = 20 - 2x 2x = 20 x = 10. Now we back-substitute this value for x into the equation for y: y = 20 - x = 20 - 10 = 10. Thus, the maximum area occurs when x = 10 and y = 10 i.e. when the shape is a square. This works for any starting value of the perimeter, and means that a square will always have more area than any rectangle with an equal perimeter.

Sorry, no US $20 gold coin is dated 1833
In 1960 I bought a US 20 dollar gold coin that is encase in a gold frame to be worn as jewelry. This coin is 1924 and was minted in San Francisco I assume as it has an s by the date. I would like to know what is the value of this coin.
A Liberty Head $20 gold coin with a grade of very fine (VF) is worth about $7,200.
About 1600.00 dollars!!!
$300
The bullion value of the coin would be based on the price of gold. The collectors value could be higher.
The value of a 20 mark gold coin from 1909 would depend on its condition, rarity, and current market demand. You would need to consult with a numismatic expert or appraiser to get an accurate valuation for this specific coin.
The coin needs to be seen for an accurate value. This issue is common with a average value of $1,400.00 to $1,500.00 for a circulated coin.
A U.S. $20 double eagle contains .96750oz of pure gold. The value just for the gold, today is about $1,200.00. The numismatic value depends on the date, mintmark and grade of the coin.
It's quite sacre, but all depends on the condition of the coin.
