I was only able to get the first and second question. Not the last two.

Req. = R1+R2 = 37 + 59 = 96 Ohms.
I = E/Req. = 43/96 = 0.448A
V1 = I*R1 = 0.448 * 37 = 16.6 Volts.
P1 = V1*I = 16.6 * 0.448 = 7.44 W.
I = E/Req. = 43/96 = 0.448A
V1 = I*R1 = 0.448 * 37 = 16.6 Volts.
P1 = V1*I = 16.6 * 0.448 = 7.44 W.
