Angle of vertical path?

  1. Sep 12, 2007 #1
    angle of vertical path????

    1. The problem statement, all variables and given/known data

    A descent vehicle landing on the moon has
    a vertical velocity toward the surface of the
    moon of 31:7 m=s. At the same time, it has a
    horizontal velocity of 58:6 m=s. the combined velocity is 66.625m/s

    At what angle with the vertical is its path?
    Answer in units of degrees

    2. Relevant equations

    i am pretty sure i need to use sin, cos or tan for this but not sure exactly how

    3. The attempt at a solution

    i had solved for the combined velocity to get the 66.625 however now i am stuck on the next step

    if it helps, draw a triangle indicating the velocity and its components. Then you can use sin, cos, or tan to find the answer

    if i draw it tho one angle has to be 90 degrees correct due to the horizontal and vertical velocity

    i just am not sure whether to use cos sin or tan to find at what angle with the vertical is its path
