Answer:
x = 17°
Two ways to solve:
Since the 130° angle is on a straight line, 180°, we can do the following:
180° - 130° = 50°
Then, a triangle's angles add up to 180
180° - 50° - 113° = x
17° = x
x = 17°
--------------------------------------
The exterior angle is equal to the two opposite interior angles added together,
130° = x + 113°
17° = x
x = 17°
Have a nice day!
