The problem says this; In triangle CDE, m

If you could also help me with the next one, it states; In triangle PQR, p = 56, r = 17, and m

That's weird, I had all the numbers in there? I'll edit it to put them back in I guess I've never seen it do that

Since it decided to delete some of my numbers:

Question 1) In triangle CDE, the measure of angle C is equal to 52, the measure of angle D is equal to 17, and e is equal to 28.6. Find c to the nearest tenth.

Question 2) In triangle PQR, p is equal to 56, r is equal to 17, and the measure of angle Q is equal to 110. Find q to the nearest tenth.
Don't know what happened with the original post, sorry about that!

First you need to draw the trinagle/s.  Do you now how to do that?

Question 1) In triangle CDE, the measure of angle C is equal to 52, the measure of angle D is equal to 17, and e is equal to 28.6. Find c to the nearest tenth.

You will need to find angle E and then use the sine rule.

Question 2) In triangle PQR, p is equal to 56, r is equal to 17, and the measure of angle Q is equal to 110. Find q to the nearest tenth.
Draw the pic and decide if you can use the sine rule or the cosine rule.

you do not need to find anything else first.

REmember:

The sine rule uses two sides and their opposite angles.  You need to have three of these and then you can find the 4th one.

The cosine rule uses  3 sides and 1 angle.  You must have three of these and then you can find the 4th.

Perhaps your real problems is that you do not know how to label / draw the triangles.

Here is a video for you to watch :)

Oh wow, I feel really dumb! My real problem was that this is a final study guide and I forgot that non-right angled triangles have law of cosine/sine instead of just using regular trigonometry. It's been a long year, thank you so much for your help!

You are very welcome. I hope you do well in your upcoming tests :)
