volt drop in resistors

[NWDS]

can some one help with this ?????

what is the VD across R4 & R5.

R1 6 ohms

R2 7 ohms paralell with R1

R 3 8 ohms series

R 4 9 ohms

R5 10 ohms in paralell with R4

supply voltage is 50v

the answer is 14.82v

thanks in advance NWDS

6x7/6+7 = 3.23ohm

9x10/9+10 = 4.73ohm

3.23 + 4.73 + 8 = 15.96ohm

50V/15.96ohm = 3.1328A

4.73ohm x 3.1328A = 14.818V

thanks again GF,I had worked out the current but had not applied ohms law correctly,

R/I = v, I had done this but was using the whole value for 5 resistors instead of only R4 & R5

thanks again
