<p>Angle ABD is also 130 – alternate interior. So angle ABC is 65. Does that get you along the way?</p>

3

<p>How do you know ABC is 65?</p>

4

<p>ABD is 130 also because the lines are parallel, then the bisector makes ABC 1/2 of whatever ABD is. </p>

<p>CAB = 50
ABC = 65
ACB = 65</p>

<p>x = 180-65
x = 115</p>

<p>Answer = D</p>
