Answer:
Step-by-step explanation:
AB represent the building. C represents the spot
The building forms right angle with the ground.
BC will be the hypotenuse and AB, AC are the legs
Use Pythagorean theorem,
AB² + AC² = BC²
AB² + 16² = 65²
AB² + 256 = 4225
AB² = 4225 - 256
= 3969
[tex]AB = \sqrt{3969} =\sqrt{63*63}[/tex]
AB = 63 m
height of the building = 63 m
