The value of a is D)73 I think because 180-107 since a straight line is 180 u just subtract the angle from it. hope this helps.

Answer:

B) 45

Step-by-step explanation:

Here, ∠LOA = 45°

Also, the line AO || MN

and, LO || LO.

Thus, ∠LOA = ∠f = 45°

And, ∠f and ∠a are vertically opposite angles. So, they both will equal.

Thus, ∠a = 45°
