Answer:
x = 30 degrees
Explanation:
Since the lines are parallel, these angles can be seen as vertical angles, which are always the same as their opposite. Therefore,
75 = 2x + 15
To solve this, you would subtract 15 from both sides, getting you closer to finding x.
75 = 2x + 15
-15 - 15
60 = 2x
Lastly, you would divide both sides to get your value for x.
60 = 2x
/2 /2
30 = x
