Answer:
The ladder reaches a height of 6 m.
Step-by-step explanation:
Given that,
Height of the ladder, H = 6.5 m
The foot of the ladder is 2.5 m from the foot of the wall.
We need to find the height does the ladder reach. If we consider a triangle in which hypotenuse is 6.5 m, foot of the ladder is 2.5 m then we need to find the height of the ladder i.e.
[tex]H^2=b^2+h^2\\\\h^2=H^2-b^2\\\\h^2=(6.5)^2-(2.5)^2\\\\h=6\ m[/tex]
The ladder reaches a height of 6 m.
