Explanation / Answer

first combine R2 and R3
R23 = 11 + 27 = 38

combine R23 and R4

1/R = 1/38 + 1/65

R234 = 23.98

Rtotal = 18 + 23.98 = 42

B)

I total = 10/42=
0.238

things in series have same current so I1 = 0.24
and thus V1 = 0.238*18=4.3

V234 = 0.238*23.98=5.7 V

so V4 = 5.7 and thus I4 = 5.707/65=0.088 A

then I23 = 5.707/38=0.15 A

so I2 =I3 = 0.150 A

V2 = 0.15 *11 = 1.7 V

V3 = 0.15*27= 4.1 V
