recall that the sum of all interior angles in a triangle is 180°, therefore


\bf \stackrel{A}{(48)}~+~\stackrel{B}{(6x-28)}~+~\stackrel{C}{2x}~=~180\implies 8x+20=180 \\\\\\ 8x=160\implies x=\cfrac{160}{8}\implies x=20\\\\ -------------------------------\\\\ \measuredangle B=6(20)-28\qquad \qquad \qquad \measuredangle C=2(20)
