Answer:

Step-by-step explanation:

Subtitute y in the first equation.

Now replace x in either equation to find y.

P=k/(q+4)^2
Replace p=2 and q=2 in the expression to find k.
Once got thr value of k, replace back in thr expression.
Then finally replace q=-2 to obtain a value for p.
See attachment file below. Follow the steps to find p.

Answer:
100 degrees
Step-by-step explanation:
Arc QM = Arc QN = 130°
Arc MN = 360 - Arc QM - Arc QN
= 360 - 2(130)
= 360 - 260
= 100°
