Answer:

21°

Step-by-step explanation:

set it up

7x-1+3x-9=180

combine like terms

10x-10=180

take the ten to the other side

10x=190

divide both sides by 10

x=19

plug x in

3(10)-9

30-9

(Incase you need it the other angle is 159°)

Answer: Option B.

Step-by-step explanation:

Given the system of inequalities:

$y$

$y>x^2-4$

The solution of the system of inequalities is the region between the parabolas. This region is: below the parabola $y=x^2+6$ and above the parabola $y=x^2-4$

Then, if a point is a solution of the system, then it must be in the region between this parabolas.

You can observe in the figure attached that the point that is in this region is the point (2,6), therefore, the answer is the option B.
