Question

cos theta(cos theta+3)=-2 solve for 180

Answer 1

This is what I have:
\[\cos \Theta(\cos \Theta + 3) = -2 \]
Do you mean Solve when Theta is 180 Degrees?

Answer 2

And is what I have written correct?

Answer 3

yes that is correct

Answer 4

i think the question asking find the theta in interval 0 <= theta <= 180

Answer 5

Not to jump in on someone elses convo but i like really need help with this..
is anyone on this thing good at geometry ?

Answer 6

yeah the question says "solve for \[\Theta if 0\le \Theta \le 180\]

Answer 7

for \[\cos \Theta \left( \cos \theta +3 \right)=-2\]
