Trigonometry:Angle of elevation&depression

ANYBODY, HELP PLEASE....
A ladder 5m long leans against a vertical wall at an angle of 70 degrees to the ground. Find and correct to 2 s.f.
1. the new angle which the ladder makes to the ground,
2. the distance the ladder slipped back on the ground from its original position.

Note: when solving, there must be diagrammatic expression.

Apparently the base of the ladder slips farther from the wall, but you've provided no information about that.

In its current form, the question seems incomplete, as it isn't clear why it refers to "the new angle" and "its original position" without explaining which position of the ladder the angle of 70 degrees relates to.

Also, the problem doesn't state whether the ground is horizontal.

The problem, as given, is incomplete (missing vital information). It doesn't have enough information with which to provide help.
