Respuesta :

Answer:

D. is the correct answer.

Explanation:

We can use sin cos tan method to solve Mx:

[tex]\frac{Mx}{5}=cos(37)[/tex]

[tex]Mx= cos(37) * 5[/tex]

[tex]Mx = 4[/tex]

So Mx should be 4 and head to right. as its positive.

We can use sin cos tan method to solve My:

[tex]\frac{My}{5} = sin(37)[/tex]

[tex]My = sin(37) * 5[/tex]

[tex]My = 3[/tex]

So My should be 3 and head to upwards. as its positive.

Final conclusion: D. is the correct answer.
