Answer:
My guess is $29
Step-by-step explanation:
So first I take the difference of the 10th and 6th month, which is 116.
I take that and divide it by 4, because that was the change in 4 months(10-6)
116÷4=29
The answer is 42.
The question is asking for angle N. We know from the question that angle N is equal to angle E (Don't think about the scale factor because it only applies to the sides. They're just trying to trick you).
To find angle E:

Move numbers to the right side:

Combine like terms:

Divide both sides by 13:

The formula for angle E:

Plug in the 8:

The angle measure of E is 42. So angle N is automatically 42 too.
To solidify, we can try to use the formula which they give us for angle N:
