Using our congruence statement 
, we know that corresponding angles match, so that means that 
. We know that 
, so that means that 
. This gives us the equation
<em /><em /><em>m</em> + 45 = 131
Subtract 45 from both sides to cancel it and we have
<em>m</em> = 86.
<em /><em /><em>m</em> + 45 = 131
