Question

more healp please @AZ

Answer 1

you don't even need to find what theta is in this problem

you can use the whole opposite, adjacent, hypotenuse thing to find a sin or cos value

then use a double angle formula to find the result

Answer 2

step 1: what are the values for the opposite, adjacent, and hypotenuse side lengths?

Answer 3

How- do i find that...

Answer 4

wait actually
I have sine

Answer 5

well... we know that
sin is opp / hyp
cos is adj / hyp
tan is opp / adj

etc

what is csc?

Answer 6

oh?

Answer 7

actually idk, uhhh

Answer 8

perf

so
if csc = -6/5

then sin = -5/6

yes?

Answer 9

right, yes, I do have sine._.

Answer 10

then
cos(2 theta) = 1 - sin^2 (theta)

Answer 11

So 1- 25/36
So
11/36
so
1/3?

Answer 12

oh... I forgot a 2

Answer 13

oh loll
so
-7/6?

Answer 14

1 - 50/36 = ?

Answer 15

actually uh
-14/36
-7/18 lol

Answer 16

ye

Answer 17

thank youuuuuu xddd
