Please cross check, the height of the tower. If the height is 60 m, then the ans is as follows otherwise, in the mentioned answer, change the height to the right one.
 
 
Here, CD = tower and AB = pole 
Let DE = x
In right triangle ADE,
tan 45 = x/AE
So, AE = x
 
In right triangle BDC,
tan 60=CD/BC
?3 = 60/x
 
From this equation, calculate x.
 
Height of the pole = CD - x
