Are you running a student version?

You may want to attached some screen dumps of your history tree and where you are getting stuck.

If not, you can always attach the file for people to look at.

‌Yes. I am using the student version. Now I just need to make the arch extrude. Thank you!

Jessica,

If I understand correctly, you will need to make a datum plane at an angle of 45 degrees along the edge, specified in the image below.  Then use this datum plane as the sketching reference.

You should get something like this:

This might help.If you have drawn a triangle,just select the angular face for sketch as highlighted in the image and cut it up to the selected face as shown in image.

From the triangle, you could also radius the 2 back edges to get the round.
