I have no idea how to set this problem up?

Three 36.0 Ω resistors are connected across the sides of an equilateral triangle ABC as shown in the figure.

What is the equivalent resistance between any two points AB, BC, AC of this circuit?

This is basically a problem involving series and parallel resistance. You should have something in your textbook that introduces this concept.

Take, say, the resistance between points A and B. To find the equivalent find the equivalent (say Rd) of Rac in series with Rbc and then find Rd in parallel with Rab. You can follow the same procedure for every two terminals.

Is there a formula of some kind to use for this since we are only given the total receptor value?

Rabtotal=[(Rac+Rbc)*Rab]/(Rac+Rbc+Rab)

The same for other ends but with different R subscripts.
