1. ## Need help with 11 Algebra 2 problems

Hello everyone.

Attached are 2 IMG_0218.jpgIMG_0219.jpgpictures of the math i need help on. I already have the answers. What I need are the steps/work. If you could post a picture with your steps written on paper that would be much appreciated. Even if you only know a few, anything helps.
thank you,
Peyton

First, post the pictures in portrait orientation (90° turn).

3. We prefer separate threads for separate exercises. Also, when people don't show where they're stuck, it's difficult to know where to tutor.

I would start by drawing a rough sketch of the angle and labeling the given information. From there, you can draw a representative right-triangle, and label the legs using the signed values -1 and -3. Next, you need to calculate the length of this triangle's hypotenuse.

Once you have all three sides of the right-triangle, you can write each of the six trigonometric functions of theta, by using the Right-Triangle Definition for each.

Have you learned the Right-Triangle Definitions for trig functions? They look like this:

sin(θ) = Opposite/Hypotenuse

sec(θ) = Hypotenuse/Opposite

et cetera … they are listed in your textbook.

If you need more help with this exercise, please post your work so far. Thank you.
