Please help solve this promblem for me and show me how to do it. Any help is greatly appreciated!

Solve for AR

You can't. There simply isn't enough information. For example, you could move point A down toward R, while moving point C to the right, keeping that angle constant.

I am assuming you are learning trigoometry
Step 1: 9.64/2=4.82 this gives the length of RC
Step 2: decide if you use tan, cos or sin-You use tan because you have a side that is adjacent to the angle and you are trying to find the side that is oppoisite
Step 3: tan(58)=x/4.82
Step 4:4.82*tan(58)=x this is the length of AR if you have a calculator you will be able to find the approximate value

You're assuming more than that.

It is not given that R is the midpoint of BC.

this is the length of AR if you have a calculator

What is this the length of if you don't have a calculator?
