Question

John puts the base of a 13 foot ladder 4 feet from the wall of his house. How far up the wall does the ladder reach? Round your answer to two decimal places.

Answer 1

Answer:

12.04 feet

Step-by-step explanation:

Applying Pythagoras theorem,

$a^{2}= b^{2} + c^{2}$

$13^{2} =4^{2} + c^{2}$

$c^{2} = 145$

c=$\sqrt{145}$

c=12.04
