HI!!

Answer 5

i guess you are supposed to figure you are in quadrant 1, otherwise you cannot know for certain what cosine or tangent is

Answer 6

yes, that's all i have learned lol

Answer 7

what you need is a good trig cheat sheet
look below

Answer 8

sine is the second coordinate
look at the unit circle on the last page of the cheat sheet
find the point where the second coordinate is \(\frac{1}{2}\)
the cosine is the first coordinate of that point

Answer 9

let me know when you see it

Answer 10

ok I found it so its, √3/2?
which must mean that tan is 1/√3?

Answer 11

yes and yes

Answer 12

THANK YOU SO MUCH!!!!!

Answer 13

although if you have answer choices, the tangent might be called \(\frac{\sqrt3}{3}\)

Answer 14

Answer 15
