This is an example of a very poor question, I am sorry you have to suffer through it.
4 meters up a ladder? How is up measured, vertically, or along the path of the ladder? Lets just assume it is not "up", not " vertically", but along the path of the ladder. THen the distance you climbed along the ladder is 4 m.
Now, how is the angle measured? At the vertical point, between the ladder and the wall? If so, then, the distance along the ladder (if 4 meters is vertical), then has to be distance= 4/sin60
Now assume the distance 4 meters is "vertical" up, and the angle 30 degrees is measured between the ground and the ladder. The distance along the ladder is now 4m/sin30= 8 m
So what I am suggesting, the problem is so poorly worded, it is not possible to answer. If you have a drawing, it would be much easier.
If you climb 4 meters up a ladder whose top is leaning against a wall at a 30° angle, the distance you climb along the ladder is
