Answer

63.2 degrees

Step-by-step explanation:

Using law of cosines: 19^2=8^2+14^2-2(8)(14) cos (x)

361=64+196-224 cos(x)

361=260-224cos(x)

101=224cos(x)

divide both sides by 224, which gets you (rounded to 4th decimal place) 0.4509. do inverse cos which gets you 63.2

The first one

Step-by-step explanation:

The second session is $5, and it will never be $10 again, so $5 sessions are unlimited which would be 5x.

So the answer is y = 10 + 5x
