To calculate and find unknown sides of the triangle:

Using the pythagroras theorem

$\text{Hyp}^2=\text{opp}^2+\text{adj}^2$

Hypotenuse = 48cm

Opposite = 36cm

Adjacent = y

$\begin{gathered} (48\operatorname{cm})^2=(36\operatorname{cm})^2+y^2 \\ 2304\operatorname{cm}=1296\operatorname{cm}^2+y^2 \\ 2304\operatorname{cm}-1296\operatorname{cm}^2=y^2 \\ 1008\operatorname{cm}^2=y^2 \\ y=\sqrt[]{1008\operatorname{cm}^2} \\ y=31.7\operatorname{cm} \end{gathered}$

Therefore the value of y = 31.7cm

Hence the correct value of y = 31.7cm
