Explanation / Answer

Given that 10V source absorbs 2.5mW power,

so the current passing through the 10V source is I = (2.5mW)/10V = 0.25mA

the same current passes through the entire circuit. so the value Vx = 6k x 0.25mA = -1.5V

a) Voltage Vba = (2Vx) + (8k x 0.25mA) + (6k x 0.25mA) = 0.5V

b) Power associated with dependent voltage source = I x 2Vx = -0.75mW

Therefore, Power absorbed by the dependent voltage source is 0.75mW
