How are angles 1 and 5 related? Based on this relationship you can set up an equation and solve it for x.

How are angles 1 and 5 related? Based on this relationship you can set up an equation and solve it for x.

Assume that the lines 'a' & 'b' are parallel.

 

[pka]

The $<<$ on liness $\bf a~\&~b$ is standard notation to indicate parallel lines.
Thus using vertical angles, corresponding angles and alternant interior angles we get:
$m(\angle1)=m(\angle 4)=m(\angle5)=m(\angle8)$
and $m(\angle 2)=m(\angle 3)=m(\angle 6)=m(\angle 7)$
Proceed with the given.
