tan(x/2)=(8/5)/(-4/5)
tan(x/2)=(8/5)(-5/4)
tan(x/2)=-2
Did I do the right evaluation?
So, wouldn't that make the answer -2?
So, is it the first and third option?
Awesome... Thank you so much!!
Oh okay, so I was correct at first, thank you!
Okay, I guess I'm viewing something wrong, could you tell me what exactly you think the answer is?
I did check on desmos, now I think it's the second, third, and fourth option, do you agree?
Thank you. It's false
Thank you!!
Thank you!
