Question

A ladder 13m long reaches along a wall of height 5m. At what distance from the wall does it foot touch the wall​

Answer 1

Answer:

We can use Pythogoras Therom

Step-by-step explanation:

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

$13^{2}$ = $5^{2}$ + $c^{2}$

$169$ = $25$ $+$ $c^{2}$

$c^{2}$ = $169$ - $25$

$c^{2}$ = $\sqrt{144}$

$c^{2}$ = $12$

The distance from the wall = $12m$
