Fire trucks with extension ladders are used regularly to remove people from burning buildings. However, they are limited in how far they can reach, by both the length of the ladder and, for stability reasons, the distance they can safely park away from the edge of the building. Assume that the ladder is at the back of the truck and its foot is 2m off the ground. 1.) Draw a diagram and label the unknown distances with pronumerals. PRODUCING: The truck is 4m away from the base of the building and the fully extended ladder reaches 16.46m up the side of the building. 2.) Use your diagram to find the length of the ladder to the nearest metre. 3.) It is decided that the trucks must park between 2m and 7.5m from buildings. What is the maximum height that the ladder can reach from each extreme postion? Thanks guys explain as well im confused. |
