Given:
Hypotenuse = 13m
Perpendicular = 12m
Find: Base.
Sol:
Use Pythagoras theorem
[tex]\text{ Hypotenuse}^2=Base^2+Perpendicular^2[/tex]
Sothe base is:
[tex]\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}[/tex]
The base of the ladder is 5m
