Question

The base of the ladder is blank meters from the wall?

Answer 1

Given:

Hypotenuse = 13m

Perpendicular = 12m

Find: Base.

Sol:

Use Pythagoras theorem

$\text{ Hypotenuse}^2=Base^2+Perpendicular^2$

Sothe base is:

$\begin{gathered} 13^2=Base^2+12^2 \\ 169=Base^2+144 \\ \text{Base}^2=169-144 \\ \text{Base}^2=25 \\ \text{Base}=\sqrt[]{25} \\ \text{Base}=5 \end{gathered}$

The base of the ladder is 5m
