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°

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: D

Step-by-step explanation:

You need a calculator for this cause the numbers are really large. I used a fx-9860GII Casio calculator. I put the equations on the graph mode. And then I got the x➡️0 for both equations.

I got x=0, y=5000 for the first equation

x=0, y=5200 for the new one.

You can see the y is (5200-5000)=200 more than the old equation. As the x is 0 for both that means the new one moved 200 up for the new one. It goes up cause its positive number .

I put the pictures so you can understand what I'm saying.
