s 11.18 m.
10 squared minus 5 squared is equal to c squared ; c = √125, which is an irrational number and must be estimated as 11.18 m.
If the ladder is 10 m long and 5 m from the base of the building, how high up the building will the ladder reach?

Apologies for the error in my initial response. Let's calculate it correctly.
Using the Pythagorean theorem:
a^2 + b^2 = c^2, where a = 5 m, b = height, and c = 10 m
5^2 + b^2 = 10^2
25 + b^2 = 100
b^2 = 100 - 25
b^2 = 75
b = √75
b ≈ 8.66 m
Therefore, the height up the building that the ladder will reach is approximately 8.66 meters.
