Answer:
The height of the building is the long leg. 12.99 foot
Step-by-step explanation:
The triangle is a 30° - 60° - 90°.
In this type of triangle the hypotenuse = the short leg × 2. (it is opposite the 30° angle). The Long leg = the short leg √3
hypotenuse is the length of the ladder.


The height of the building is the long leg. 12.99 foot
Answer:
height of the building is 12.99 feet.
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:



Therefore the height of the building is 12.99 feet.
