<PRE><B>Question 1159036</B>
Something is wrong in the descriptive part for your missing diagram.


-------------------------------------------------------------------
 ( 45 degrees left corner , 35 degrees right corner, and the hypotenuse side of the triangle is 3000ft as stated)
------------------------------------------------------------------


Those angles do not make for a right triangle and so this triangle has NO hypotenuse.

okay, then not a hypotenuse; just the long side is 3000.  The angle opposite is 100 degrees.   You can use Law Of Sines.</PRE>
