Answer-
The value of x is 10
Solution-
When two lines are crossed by another line (transversal), the angles in matching corners are called Corresponding Angles.
When the line are parallel the corresponding angles are equal in measurement.
As m and n are parallel line, so
\(\Rightarrow 8x+50=130\)
\(\Rightarrow 8x=130-50\)
\(\Rightarrow 8x=80\)
\(\Rightarrow x=10\)
