Answer:

x = -10

Step-by-step explanation:

1) <em>A line creates a 180° angle on each side of it. Even if another line intersects it, we know that the total measure of angles on that side will equal 180°.</em>

2)<em> We set the equations equal to 180.</em>

(-4x) + (-14x) = 180

<em>Combine like-terms</em>

-18x = 180

<em>Isolate </em><em>x</em><em> by dividing both sides by </em><em>-18.</em>

x = -10

3)<em> </em><em>To solve for each angle, you can plug in </em><em>-10</em><em> for </em><em>x</em><em> and solve.</em>

-4(-10) = 40°

-14(-10) = 140°
