How Do You Calculate Angle 2 in a Physics Vector Problem?

In summary, the conversation is about a physics problem where angle 1 is given and angle 2 needs to be found. The dark red arrow represents a vector and the problem involves finding something else. The solution involves adding another line parallel to the ground and using the fact that the angles are congruent and perpendicular. The picture provided shows how the angles are related and how angle 2 can be found using the given information.

So angle 1 was giving and through that they found angle 2. I need help on how they found angle 2. The dark red arrow is a vector. This is a physics problem asking for something else but I got stuck here lol.

Add another line parallel to ground intersect x-y origin.

The angles are congruent as their arms are pairwise perpendicular. The red vector is vertical, makes a right angle with the horizontal arm of angle 1. The other arm of angle 2 is perpendicular to the slope which is the other arm of angle 1. See picture: β=90-(90-α)=α.

What happened with the x axis? I updated the picture to look better.

It is difficult to provide a specific response without more context or information about the problem. However, one possible approach to finding angle 2 could be to use the law of cosines or the law of sines, depending on the given information and known angles or sides. Another approach could be to use vector analysis techniques, such as the dot product or cross product, to find the angle between the two vectors. It would be helpful to provide more details about the problem and any attempts or ideas you have already tried.
