Answer: 97 meters

Step-by-step explanation:

Draw 2 right triangles KLM and ABC.

ML=3.2 m ( is a pole) KL =1.29 m( pole's shadow).

(The triangle KLM is right because we suppose that pole is staying vertically).

In triangle AB is tower's shadow= 39.25 m and BC is the height og tower=x meters?

Triangles KLM and ABC are similar .

So ML/KL=x/AB

3.2/1.29=x/39.25

x=3.2*39.25/1.29= approx 97.36 meters= 97 meters
