The equation: n - 4 = -15
Now let's solve our equation for n.
n - 4 = -15

n = -11
Answer:
C
Step-by-step explanation:
If x was equal to 12, 22.5 or 10 the side would be too large compared to 15. This is only correct if the drawing is to scale, however.

i cant explain it right now i have work to do so sorry:)
x=84
Add up all the sides and then subtract that number by the original amount of degrees. 540
