The foot of the leaning against the wall is 5ft away from the wall and its top is 12ft. Above the ground. What is the length of the ladder?

✏️RIGHT TRIANGLE

===============================

Problem: The foot of the leaning against the wall is 5ft away from the wall and its top is 12ft above the ground. What is the length of the ladder?

Solution: Apply the Pythagorean Theorem to find the length of the ladder.

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

${c}^{2} = {5}^{2} + {12}^{2}$

${c}^{2} = 25 + 144$

${c}^{2} = 169$

$\sqrt{ {c}^{2} } = \sqrt{169}$

$c = 13$

– Therefore, the length of the ladder is:

$\large \rm Hypotenuse = \boxed{ \rm \green{ \: 13 \: ft \: }}$
