Answer:
C. 8
Step-by-step explanation:
I almost thought this was going to be Pythagorean Theorem, but no.
Use Cosine Law:
cos θ = 
θ = cos−1(0.6)
θ = 53.130...
Now use the SOHCAHTOA ratio for sine (
) to find x now that you have one angle:
sin θ = 
x = 10sinθ (θ isn't needed to be written out as it is shown in the equation above)
x = 8
Parameters of functions are the independent variable(s). e.x. y = 2x /\ x is the independent <span> variable (the parameter).</span>
Answer:7
Step-by-step explanation:
A) x= -21/-3
= 7 answer
B is your answer if you need me to explain why just ask me :) have a good day
It is rational because it is a terminating decimal. It can be represented as a ratio of two integers (121/10)
