Answer:
x = 0
Step-by-step explanation:
the origin
We know that
if <span>90° < θ < 180°
</span>then
θ--------------> belong to the second quadrant
so
tan θ is negative
sin² θ + cos² θ=1----------> sin² θ=1-cos² θ----->sin² θ=1-(-2/9)²
sin² θ=1-(4/81)------> 77/81----------> sin θ=√(77/81)------> √77/9
sin θ=(√77)/9
tan θ=sin θ/cos θ------> [(√77)/9]/[-2/9]-------> -√77/2
the answer is the option
<span>A) -77sqroot/2</span>

Answer:
B
Step-by-step explanation:
f(x) = 4x - 7
What does f(x) mean? It means that whatever variable you have on the left which is (x), the same variable must be on the right.
So f(2) means that whatever variable is on the right, it must be replaced with 2 on the right. So .....
f(2) = 4(2) - 7
f(2) = 8 - 7
f(2) = 1
