Question

The perimeter of the triangle below is 53 units. Find the length of side WX. Write your answer without variables.

Answer 1

$3y~~ + ~~(2y+3)~~ + ~~\stackrel{WX}{(y+2)}~~ = ~~53\implies 6y+5=53\implies 6y=48 \\\\\\ y=\cfrac{48}{6}\implies y=8\hspace{15em}\underset{\textit{ WX}}{\stackrel{8~~ + ~~2}{\text{\LARGE 10}}}$
