Step-by-step explanation:

given, try to analyse:

ladder 15 feet long.
60 degree angle to the ground.

the height of the building is opposite to the angle 60° and given hypotenuse, the ladder of 15 feet long.

using sine rule:

$sin(x) = \frac{opposite}{hypotenuse}$

$sin(60) = \frac{opposite}{15}$

$opposite = sin(60) *15$

$opposite = 12.99feet$

Therefore the height of the building is 12.99 feet.
