The angle θ has the point (–2, 9) on its terminal side. What is the exact value of each of the following?  The adj. side of this angles is -2; the opp. side is 9.  What is the hypo?  Use the Pyth. Them.

Then the sine of this angle is    opp / hyp.

And so on.

Just the words

How do I get that if the side length is negative?

jhonyy9 · Answer

make the calculi so and than will result negativ so just will get in what quadran will be theta

mathmale · Answer

If the adjacent side is -2 and the opp. side is 9, then the Pyth. Thm. tells us

that the hyp. is Sqrt( (-2)^2 + 9^2).  Does this answer your question?

Thank you

anonymous · Answer

So the hypotenuse is 9.22?

mathmale · Answer

Yes.  or  you could leave it as is, without changing it to a decimal fraaction.

Then sin of this angle   =   Opp  /   Hyp    =    9 / Sqrt (85).

anonymous · Answer

Thanks man. So, for the rest I just find the cos and tan normally?

anonymous · Answer

Answer:
The Sine is 0.976
The Cosine is -0.216
and The Tangent is -4.5
Is that right?
