Question: A ladder rests against a wall making an angle $\alpha $with the horizontal. The foot of the ladder is pulled away from the wall through a distance x, so that it slides a distance y down the wall making an angle$\beta $with the horizontal. The correct relation is


1) $x=y\tan \frac{\alpha +\beta }{2}$
2) $y=x\tan \frac{\alpha +\beta }{2}$
3) $x=y\tan (\alpha +\beta )$
4) $y=x\tan (\alpha +\beta )$
Solution: Explanation: No Explanation
Height and Distance
