Help me please sos

    Help me please!! sos

    A man pushing a mop across a floor causes the mop to undergo two displacements. The first has a magnitude of 167cm and makes an angle 161 degrees with the positive x- axis. The resultant displacement has a magnitude of 168 cm and is directed at an angle of 37.6 degrees to the positive x- axis.

    Find the magnitude of the second diplacement?
    Find the direction of the second displacement with respect to the positive x-axis.( Consider counterclockwise to be positiveand answer within the limits of -180 degrees to180 degrees)
    Now I have attempted this numerous times from many different views but have failed miserably. I enetered in as the online homework an got it wrong all 7 times only to find out that the answer is 294. Could someone please help me figure out how to solve this so that i may continue to the next problem, because it is a play on this one.

    What is the x-component and y-component of displacement 1?

    What is the x-component and y-component of net displacement?

    x-componnet of displacement 1 + x-component of displacement 2 = x-component of net displacement

    y-componnet of displacement 1 + y-component of displacement 2 = y-component of net displacement
