I put it in a url again because I can't seem to upload the picture. Thank you all for your help with these.
+9479 Gwendolynkristine, here's a trick you can use to get the picture to show:
Go to the link you just posted. Right click on the picture and select " Copy image URL / Address / Location " * . Then, on this website click the " Image " button like normal and right under where it says URL, paste the URL that you copied. 
*
If you are using Internet Explorer, select "Properties" and copy the address next to "Address (URL)"
-----------------------------------------------------
Let's call the base = 12.5
That makes the height = 15sin77º
area = (1/2)(base)(height)
area = (1/2)(12.5)(15sin77º)
area = 93.75sin77º
area ≈ 91.35 sq. un.
