Measure of a straight line is 180°
Let's consider the interior angles as P and Q respectively.
P + 110° = 180°
P = 180° - 110°
P = 70°
Q + 120° = 180°
Q = 180° - 120°
Q = 60°
We know that the sum of all angles of a triangle is 180°
60° + 70° + x = 180°
130° + x = 180°
x = 180° - 130°
x = 50°

This is a very simple question. Hope you like it and give a 5 star rating to me!
Step-by-step explanation:
First Step: 110 + interior angle = 180 degree
interior angle = 180 - 110
interior angle = 70 degree (linear pair)
Second Step: 120 + interior angle = 180
interior angle = 180 - 120
interior angle = 60 degree (linear pair)
Third Step: (By angle sum property)
x + 60 + 70 = 180
x + 130 = 180
x = 180 - 130
x = 50 degree
