A ladder set against a wall at an angle 45
to the ground. If the foot of the ladder is pulled away from the wall through a distance of 4 m, its top slides a distance of 3 m down the wall making an angle 30
with the ground. Find the final height of the top of the ladder from the ground and length of the ladder

Sir why can not we take tan theta instead of sin theta ?

You can take but you will not get same answer Yes this question is not correct fully either the angles are wrongly given or the distance are not proper. Using both the methods are giving different answer. So according to board whatever method you apply you get full marks. One more thing. This question very much related to 'NCERT EXAMPLER ' question page 100.

Exactly, with tan it's 9.56 something, and using sin it's 7.56
