<PRE><B>Question 698344</B>
&lt;br&gt;&lt;font face=&quot;Tahoma&quot;&gt;Since we are given that it is a 30-60-90 right triangle, this should be a quick problem!&lt;br&gt;

In any given 30-60-90 right triangle, we have a certain relationship between the legs.&lt;br&gt;

One relationship, is that the hypotenuse is always equal to 2 times the shortest leg.&lt;br&gt;

Also, we know that the longer leg is always equal to the shorter leg times the square root of 3.&lt;br&gt;

So, since we know the short leg is 97 inches (because it is NOT the height),&lt;br&gt;

then we know that the height of the tree is {{{97*sqrt(3)}}} inches,&lt;br&gt;

which is about 168 inches almost exactly.&lt;br&gt;

I hope this helps!  Keep practicing!  :)&lt;br&gt;
