Answer:

x = -10

Explanation:

1) 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°.

2) We set the equations equal to 180.

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

Combine like-terms

-18x = 180

Isolate x by dividing both sides by -18.

x = -10

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

-4(-10) = 40°

-14(-10) = 140°
