(6x -9) + 5= 2
= -54 + 5
= 2
Hi there! Use the following identities below to help with your problem.

What we know is our tangent value. We are going to use the tan²θ+1 = sec²θ to find the value of cosθ. Substitute tanθ = 4 in the second identity.

As we know, sec²θ = 1/cos²θ.

And thus,

Since the given domain is 180° < θ < 360°. Thus, the cosθ < 0.

Then use the Identity of sinθ = tanθcosθ to find the sinθ.

Answer
- sinθ = -4sqrt(17)/17 or A choice.
Answer:
h(-6) = -22
Step-by-step explanation:
h(n) = 3n - 4
h(-6)= 3(-6) - 4
= -18 - 4
= -22
X=9
3x-12=x+6
2x-12=6
2x=18
X=9
