tan is equal to -5/12

Answer 9

you just said -5/13 ?

Answer 10

sorry it was a typo

I also meant like what is tan equal to in relationship to the sides. Is it Opposite over hypotenuse? adjacent over hypotenuse? opposite over adjacent?

Answer 12

opposite over adjacent

Answer 13

Answer 14

i found the hypotenuse and I got -5/13

Answer 15

as the final answer

Answer 16

I'm stuck, one sec @Jamierox4ev3r @sleepyjess help me out? :P

Answer 17

aye this was forever ago... i literally don't remember v.v

Answer 18

So if we solve for x we get the hypotenuse

Answer 19

it's fine, I got it, thank you though!

Answer 20

And so since Cos has to be positive it doesn't make a difference because if cos is + then sin can be - or +

Answer 21

I made a story board for ya! Remember, "All Students Take Calculus"! Regards
