I successfully solved R2, and R3.
I do not know how to solve R1, I've tried a few things that got flagged as wrong. I'm not sure how to proceed.

 

You probably need to explain the question as that picture does not make much sense to me.
Is there a circuit involved?
What values are you trying to solve?

To quote The Hitch Hiker's Guide to the Galaxy, “We demand rigidly defined areas of doubt and uncertainty”.

I think their website is busted
It is supposed to be a circuit. I belive R2, R3 are in series. I need to solve R1 Ohms, V, mA, mW and also the Total Ohms, V, mA , mW.
The information provided was
Total: mW 3170
R3: 360 mW
R2: 8.51V , 200mW
I solved R2 and R3. But this information doesnt work for R1.

 

I reckon R2 and R3 are in parallel, with R1 in series.
So, work out the total current, that is, I(R2) + I(R3) and then, use that to find the resistance of R1 as you now have the current and the power.
