I don't have an attempt. I only know that angle R is 90 degrees because it's a tangent line.

what is a tangent line?

Answer 4

I thought it was a line that touches the circle at one point.

Answer 5

so how did you conclude that angle R is 90 degrees?

Answer 6

I thought that it was. If I'm wrong(it sounds like I am), can you help me?

Answer 7

what kind of information does the mRS = 84 degrees give you?

Answer 8

To other people, probably something useful. To me, nothing. I don't know how to use that information to answer this problem.

Answer 9

>.< how about learn what those symbols meant?

Answer 10
