If a 10m ladder stands 1.25m from a wall, what is it's reach?
1.25^2 + b^2 = 10^2
1.5625 + b^2 = 100
b^2 = 98.4375
b = ?
the ladder will 9.9m on the wall
10 meters - 1,25 = 8,75
To find the reach of the ladder, we need to know the distance from the top of the ladder to the wall. In this case, the distance from the top of the ladder to the wall is equal to the height of the ladder minus the distance of the ladder's base from the wall.
Given that the ladder's height is 10m and it stands 1.25m from the wall, we can calculate the reach of the ladder as follows:
Reach = Height of the ladder - Distance of the ladder's base from the wall
= 10m - 1.25m
= 8.75m
Therefore, the reach of the ladder is 8.75 meters.
