Answer:
A: C = 15N
Step-by-step explanation:
30/2 = 15 (the cost of 1 class)
Answer:
x=20. y=15
Step-by-step explanation:
in similar triangles the sides are all in proportion. this means:


so:

x=5×4
x=20
and...

y=3×5
y=15
Answer:
D 5/3
Step-by-step explanation:
Secθ= Hypotenuse/Adjacent
Secθ=10/6
Simplify: 10/6 -->5/3
Ans: D 5/3
remember your six trigonometric functions:
Sinθ=Opp/Hyp -->Cscθ=Adj/Hyp
Cosθ=Adj/Hyp -->Secθ=Hyp/Adj
Tanθ=Opp/Adj-->Cotθ=Opp?Adj
It is basically the opposite of each other, don't forget when you are at the last step you simplify! never forget. Also working with square roots will be a bit tricky when converting to Csc/ Sec/ Cot. Just noting you that Square roots don't belong in denominators!
Answer:
if x is 6 or lower (you didnt link anything)
