About 15 degrees. Many, if not most, extension ladders today have a sticker on the side that shows a line that should be parallel to the ground when the ladder is at the proper safe angle.
Well it depends on what ladder it is some are safe some are not
The angle of inclination.

Lean a ladder against a wall. Not too steep . . . Give it a nice angle, for safe climbing. The height is the distance between the ground and the place where it hits the wall. The slant height is the length of the ladder.

Angle of inclination is a fancy term for earths tilt. So the angle of inclination is 23 1/2 %.
The angle of inclination.
In the context of satellites, the inclination angle is the angle between the equator and the polar orbit. The polar satellite has high angle of 90 Deg and the Geo SAT has angle of 0 Deg

Hold a ruler level, then slope the ruler to an angle of 45 degrees. The inclination of the ruler is now 45 degrees. So if rock has been altered as to be unlevel, then the angle from the level is the rock beds inclination.
