<PRE><B>Question 778389</B>
Let point D be a point that is on line L, but it is to the left of point A


The angle BAD is composed like this


m &lt; BAD = m &lt; BAC + 37


since lines L and M are parallel, this means that angle BAD and the 105 degree angle are equal (they are alternate interior angles), so this means


m &lt; BAD = m &lt; BAC + 37


105 = m &lt; BAC + 37


105-37 = m &lt; BAC


68 = m &lt; BAC


m &lt; BAC = &lt;font color=&quot;red&quot;&gt;68 degrees&lt;/font&gt;</PRE>
