It's very simple...

 

Let's find the angle using the tree height and the length of the shadow.

 

Tree height   Ht = 30 ft

 

Length of the shadow is 65 ft

 

Length of the tree shadow is  65 ft - 25 ft = 40 ft

 

Angle   A = ?                tan(A) = 30/40 ≈ 36.87°

 

Pole height    Hp = tan(A) * 65 = 48.75 ft   indecision
