Answer:
56 m
Explanation:
There is a right triangle formed between the height of the tower and Khaled.
The hypotenuse is the distance from the top of the tower to Khaled's feet
The legs are 33 and height h , then
h² + 33² = 65²
h² + 1089 = 4225 ( subtract 1089 from both sides )
h² = 3136 ( take square root of both sides )
h =
= 56
The height of the tower is 56 m
