It's simple. 13 and 4 are parallel. Find a replacement for that first. You'll end up with 3 resistors. Find a replacement for them. You'll end up with one resistor. So no you have one known voltage and one known resistance, you can plug the values into ohm's law and calculate the current.

Formula for resistors in parallel is: Rt=1:((1:R1) + (1:R2)+(1:R3)) and so on and for series resistors just add the values Rt= R1+R2+R3 and so on

Or, with just two parallel resistors, simpler R1*R2/(R1+R2)
