Answer:

D. is the correct answer.

Step-by-step explanation:

We can use sin cos tan method to solve Mx:


(Mx)/(5)=cos(37)


Mx= cos(37) * 5


Mx = 4

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

We can use sin cos tan method to solve My:


(My)/(5) = sin(37)


My = sin(37) * 5


My = 3

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

Final conclusion: D. is the correct answer.
