According to trigonometry in a right triangle:

Let x be the height of the tower.
Given ,

Since tower stands vertical to the ground, that means it is making a right triangle with the shadow.
![\tan 65^(\circ)=(x)/(60)\\\\\Rightarrow\ 2.1445=(x)/(60)\ \ \text{[Using calculator]}\\\\\Rightarrow x= 2.1445*60=128.67\approx129\text{ feet}](https://img.qammunity.org/2021/formulas/mathematics/college/929cchrrqsm56dowhutmjea59m1wyb0hp0.png)
