Question

Which of the following equation can be used to find the length of LN in the triangle below?

Answer 1

Given a right angled triangle LMN;

Where MN is the hypothenus;

let LM be the opposite;

then LN is the adjacent.

By the pythagoras theorem;

`\begin{gathered} \text{Where h=hypotenus, o=opposite and a=adjacent} \\ h^2=o^2+a^2 \\ o^2=h^2-a^2 \\ a^2=h^2-o^2 \end{gathered}`
`\begin{gathered} h=33,\text{ o=11 and a=LN} \\ (LN)^2=33^2-11^2 \end{gathered}`
