Answer:

Step-by-step explanation:

Given:

To find:

The value of y

We'll go ahead and use the cosine rule to find the value of y as seen below;

$y^2=e^2+s^2-2es\cos E$
$\begin{gathered} y^2=42^2+32^2-2*42*32*\cos78 \\ y^2=1764+1024-558.8666 \\ y^2=2788-558.8666 \\ y=√(2229.1334) \\ y=47.2\text{ cm} \end{gathered}$

Therefore, the value of y is 47.2 cm
