Angles on a straight line add up to 180 degrees.

180 - 105 = 75

Angles in a triangle add up to 180 degrees.

180 - 55 - 75 = x

Answer:

Option D

Explanation:

The measure of the exterior angle is equal to the sum og non-adjacent interior angle

=> 105 = 55 + x

Subtracting 55 to both sides

=> x = 105-55

=> x = 50 degrees
