Answer is in the attachment below.
To find sec θ given sin θ = − 5 2 and 0"> tan θ > 0 , we determined that θ is in the third quadrant. Using the Pythagorean identity, we found cos θ = − 5 21 and thus sec θ = − 21 5 21 .

Nice story, glad to hear it. I like biology, science, or physic. Sometimes, I like to joining a history class. They discuss about something happens in the past and the secret history. Biology, I had studied it when i was in junior school. The old name is IPA, Natural science. I studied about human's body, sciences, natures, and anything interesting to know. Physic, honestly I don't like when i see some formulas. It's same reason, if I don't like math too.I don't have any activities at school so I just go to the canteen and enjoy the foods or drinks to spending my time in rest time.
