Given is a triangle. As we know, the sum of all the interior angles in a triangle is 180 degrees, we have,


\begin{gathered} 7x-2+4x+5x-10=180 \\ 16x=180+2+10 \\ 16x=192 \\ x=(192)/(16)=12 \end{gathered}

The angle A is 4x, therefore, the value can be calculated by substituting for x. We have,


4x=4*12=48

Thus, A = 48 degrees.

SImilarly, we get,


\begin{gathered} B=7x-2=7*12-2=82 \\ C=5x-10=5*12-10=50 \end{gathered}
