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
$$\therefore 3x+10+2x+30= 180^{o}$$
$$\therefore 5x+40 = 180^{o}$$
$$\therefore 5x = 140$$
$$\therefore x = \dfrac{140}{5} =28^{o}$$
$$x= 28^{o} $$
