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?

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
