<PRE><B>Question 827317</B>
We have a right triangle with leg lengths of 2 and 11
We can find the measure of the angle opposite
the 2 length side by using tangent
tan(x) = opposite/adjacent
tan(x) = 2/11
so arctan(2/11) = 10.3 degrees
check out http://www.wolframalpha.com/input/?i=arctan%282%2F11%29

Since the 3 angles = 180
90 + 10.3 + x = 180
 100.3 + x = 180
  x = 180 - 100.3 = 79.7 degrees

The three angles are 90, 10.3 and 79.7</PRE>
