I just need to be walked through the process again, its the example option so dont worry!

Given:
The length of the hypotenuse side is 28.
The length of the opposite side is 24.
To find the length of the adjacent side:
Let x be the length of the adjacent side
Using the Pythagoras theorem,
[tex]\begin{gathered} \text{hyp}^2=\text{opp}^2+\text{adj}^2 \\ 28^2=24^2+x^2 \\ 784=576+x^2 \\ x^2=784-576 \\ x^2=208 \\ x=\sqrt[]{208} \\ \approx14.4 \end{gathered}[/tex]Hence, the answer is 14.4.
