Mathematics

Find the value of x in each of the following diagrams


SOLUTION
In the given diagram, A is a straight line, and angle formed on a straight line is $$180$$ degree.
so, 
$$2x+x= { 180^o } $$
 $$3x= { 180^o } $$
 $$x=\dfrac { { 180 ^o }  }{ 3 } = { 60 ^o } $$
so  $$ x= { 60 ^o }$$ 
$$2x=$$ $$ { 120 ^o } $$
