Answer 2

$\underline{\bold{If\: the \:top \:of\: ladder\: of\: length\: is \:15\: m \:and}}$ $\underline{\bold{ladder \:reached \:a \:window\: 9 \:m \:above\: the}}$ $\underline{\bold{ground.\: What\: is\: the \:distance\: between}}$ $\underline{\bold{the\: base \:of \:the \:ladder \:and \:the \: wall \:?}}$

$\bold{\red{Solution\::}}$

Length of ladder (H = Hypoteneous) = 15 m

Height of ladder (P = Perpendicular) = 9 m

We have to find the distance between the ladder and the wall. (B = Base) = ?

Now...

In ∆ABC

According to Pythagoras Theorem;

(H)² = (P)² + (B)²

(AC)² = (AB)² + (BC)²

(15)² = (9)² + (B)²

225 = 81 + (B)²

225 - 81 = (B)²

144 = (B)²

(B)² = 144

B = √144

$\boxed{B\: = \:12 \:m}$

So, the distance between the ladder and the wall is 12 m.
