It's the first one---------------------
Answer:
it could maybe 50 or 525 hope this helps idrk
Step-by-step explanation:
since you have the 75, we know that a would equal 105 for line g , since a line = 180 degrees
so to make line f parallel with g it needs the same angles with line n as line g has
so if a = 105, then angle d would also need to be 105
The answer is D
