Hey there Smarty!
Your answer, would be the first option. I used a graphing calculater to recheck my work for this problem, and because of this reconfirmation, I concluded that you first answer would
option (a).Hope this helps you!
Using Sine.
Sine = Opposite / Hypotenuse
sin 60° = a / (6√3) But sin60° = √3/2
√3/2 = a/(6√3)
Cross multiply
2*a = 6√3 * √3
2a = 6 * √(3*3)
2a = 6*3
a = 6*3/2
a = 3*3 = 9
Option E.
Hope this helps.
Answer:
Step-by-step explanation:
distance between center and (1,-2) is
distance of the point from the center>radius of circle.
So it lies outside the circle.
