Because the horizontal lines are parallel, we conclude that:
x = 105°.
How to find the value of x?
If you look at the image, you can see that the two horizontal lines are parallel.
From that, we can conclude that x and the top left angle (the one that measures 75°) are supplementary angles.
Where two supplementary angles are these that add up to 180°, then we have:
x + 75° = 180°
Now we can solve that for x:
x = 180° - 75° = 105°.
So we conclude that x measures 105°.
