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. Last edited by skipjack; August 22nd, 2018 at 05:49 PM.

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.
