Question

The top of a building is 65 meters away from a spot located 16 meters away from the foot of the building what is the height of the building

Answer 1

81

Explanation:

65 meters plus the 16 is 81

Answer 2

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

`AB = √(3969) =√(63*63)`

AB = 63 m

height of the building = 63 m
