Answer:

P = 303N

Explanation:

The diagram was missing. Attached you can find the correct diagram.

With a sum of forces on box A:

[tex]T-F_{fa}=0[/tex]    where [tex]F_{fa}=\mu s*m*g[/tex]

Solving for T:

[tex]T=\mu s*m*g[/tex]

T=136N

Now, on box B:

[tex]P*cos\theta-T-F_{fb}=0[/tex]  Where T=136N;  [tex]F_{fb}=\mu s*m*g[/tex]

Solving for P:

[tex]P = \frac{T+F_{fb}}{cos\theta}[/tex]

P = 303N
