Transmission-line power splitter problem

[reddvoid]

Homework Statement

Here R1 and R2 are to be fed in phase from a 100 ohm line with R1 receiving twice the power of R2 ...how to find Z1 and l1
Z2 and l2

to find power delivered to load we need transmission coefficient ??

i don't understand the meaning of "fed in phase"

Homework Equations P = [(V^2)/R]The Attempt at a Solution Assuming R1 and R2 are in series, the equivalent resistance from the 100 ohm line is R1+R2. We can then find the voltage across each resistor using Ohm's law: V = (R1+R2)I. Since R1 is receiving twice the power, we can set up the following equation: R1I^2 = 2(R2I^2)From this equation we can solve for I and then use that to find V. Once we have V, we can find the impedance of each resistor (Z1 and Z2) using the following formula: Z = V/I We can also find the power delivered to each load using the equation: P = [(V^2)/R]. I'm not sure what transmission coefficient has to do with this problem though.
