Tan (t) = –3, where t lies in Quadrant II. Use a right triangle to

find the other five trig functions of t?

So I know that tan = opp/adj and that Quadrant 2 is where x is negative and y is positive. And I know the trig functions sin cos sec cosec and cotan, but I have no idea how to go about solving this.

Can anyone please help me?

Thank you so much!

A 475-foot tall monument is located in the distance. From a window in a building, a person determines that the angle of elevation to the top of the monument is 18∘, and the angle of depression is 2∘. How far is the person from the monument?

So, I'm still not sure how to set up the problem. I know that I can label the monument as a side of a triangle that is 475 feet. And then angle of elevation is from the ground to the top of the building. So I set up tan18 degrees = 475/adjacent side. But I keep getting the problem wrong?

Could someone please help me with this?

I really need help.

Thank you so much!

I'm a freshman in high school, and I want to join a sports team.

I just wanted to know, do they meet on weekends? If so, for how long?

I'm considering fall, winter and spring track.

Thanks!
