Use the law of cosines:
c² = 8² + 11² - 2•8•11 cos(37°)
c² ≈ 44.4402
c ≈ 6.66634
Answer:
∅ = 50°
Step-by-step explanation:
YOU NEED A CALCULATOR TO SOLVE THIS!
You need to use Law of Sines
Here you will be doing 
a and c are the lengths, while A and C are the angles
you want to get the denominators out from underneath so multiply both sides by sinA and sin43
Now you want to get sinA alone so divide both sides by 2.54
now get A alone
put that into the calculator
Answer:
$2.35 for one video
Step-by-step explanation:
You set up two equations:
$7.50= p + 2v
$12.20= p + 4v
You then set both equal to p
p=-4v+12.20 and p=-2v+7.50
So you can set them equal to each other and solve for v (the cost of one video)
v= $2.35
Answer: -29
Subtract 18 FROM -11.
That means that 18 would go after -11.
-11 - 18 = -29
Answer:
The correct answer there is the first option
