Answer:
The first one is the answer to the question
Answer:
The answer to your question is: the first option - 9/ 
Step-by-step explanation:
Process
cosФ = adjacent side / hypotenuse
-1/9 = adjacent side / hypotenuse
adjacent side = -1 hypotenuse = 9
c² = a² + b²
b² = c² - a²
b² = 81 - 1
b =
b = opposite side
But b is negative because we are in the third quadrant.
b = -
Finally csc Ф = hypotenuse / opposite side
csc Ф = - 9 / 
Divide both sides by -3
y + 5 = -15/3
Simplify 15/3 to 5
y + 5 = -5
Subtract 5 from both sides
y = -5 - 5
Simplify -5 - 5 to -10
y = -10
-18/8 = -2.25
therefore C is less than -2.25
Answer:
$600
Step-by-step explanation:
Omar spent $600.
Essentially, we divide his total number of points:
1800
by the amount earned
300
=
6
we take that and multiply by 100 (our amount needed to be spent to earn points) and boom, problem solved.
