See figure
Tan 45 = h/x+10 =1
h=x+10
tan 60 = h/x= root 3
h = x(root 3)
x=10/( root3 -1)
And h=10(root3)/(root3-1)
Tan 45 = h/x+10 =1
h=x+10
tan 60 = h/x= root 3
h = x(root 3)
x=10/( root3 -1)
And h=10(root3)/(root3-1)

FRIEND SECOND PART PLEASE ...
Second part....?
DISTANCE OF THE POINT FROM THE BASE OF THE PILLAR ??
That is x which is equal to 10/(root3 -1)
OK... THANKS ...
