Consider XY plane.
Assume the motion is in +X direction it means acceleration is in +X direction.
The gravity acts in -Y direction.
Now make a vector diagram;
The required angle is in between base (x-axis) and hypotenuse. Right?
Now,
As we know that tan(x) = perpendicular/base.
So
Tan(x) = g/a.

Assuming motion in XZ plane:
tan(@) = (Acceleration in X axis)/((Gravity+ acceleration in z axis).
Here, acceleration in z axis = 0.
tan(@) = (Acceleration in X axis)/((Gravity+ acceleration in z axis).
Here, acceleration in z axis = 0.

Here angle is to be measured with the free surface, so answer will be g/a.
