Question

A ladder is placed in a slanting position against a wall such that it touches it, 24 m above  the ground. The foot of the ladder is 18 m away from the bottom of the building. What is  the length of the ladder?​

Answer: AC=30m,length of ladder

SOLUTION

Let AC be the ladder and BC be the wall . Then,

In right △ ABC,

⇒AC²=AB²+BC²

⇒AC²=24²+18²

⇒AC²=900

⇒AC=√900

⇒AC=30m

Answer 2

Answer:

30m is the length of the ladder

Step-by-step explanation:

→ In right ∆ ABC

→ AC² = AB² + BC²

→ AC² = (24)² + (18)²

→ AC² = 576 + 324

→ AC² = 900

→ AC = √900

→ AC = 30m

=> Thus, the length of the ladder is 30m
