We'll see the tree with the shadow:
{{{drawing(400,400,-1,10,-1,5,line(0,0,0,4),line(0,4,.2,4),line(.2,4,.2,0),line(.2,0,0,0),green(line(-1,0,10,0)),green(line(.2,4,9.5,0)),locate(4,3,26m),red(locate(8,.5,24^o)),locate(-.3,3,h))}}}
By Trigo Function:
{{{sin24^o=opp/hyp=h/26m}}}
{{{h=(sin24^o)(26m)=10.57m}}}
<font color=blue>h = 11 meters</font>


Thank you,
