Question

An evacuation slide of an aircraft is 73 feet long. It is 55 feet from the airplane horizontally. What is its height at the top?

Answer 1

Step-by-step explanation:

in triangle ABC, ABC=90

Let AC be 73 & BC be 55.

square of AB= square of AC - square of BC ( by Pythagoras theorem)

therefore AB = 48

hence , the height at the top is 48 feet.
