The two angles $\left(3x+10\right)^{o}$ and $\left(2x+30\right)^{o}$ will make a straight line then find $x$?

SOLUTION
Two angles $(3x+10)^{o}$ and $(2x+30)^{o}$ make straight line
$\therefore 3x+10+2x+30= 180^{o}$
$\therefore 5x+40 = 180^{o}$
$\therefore 5x = 140$
$\therefore x = \dfrac{140}{5} =28^{o}$
$x= 28^{o}$
