Answer 1

In a right-angled triangle, the Pythagoras theorem holds:

`\text{Hypothenus}^2=opposite^2+adjacent^2`

We are given :

Hypothenus = 24

opposite = 16

adjacent = x

Substituting and simplifying, we have:

`\begin{gathered} 24^2=16^2+x^2\text{ } \\ x^2\text{ = 320} \\ x\text{ = }\sqrt[]{64\text{ }*\text{ 5}} \\ x\text{ = 8}\sqrt[]{5} \end{gathered}`
