The answer is D because both statements are giving us the chance to apply pythogorous theorem to find out the required individually.

However, (1) & (2) result in different answers.

That might be a reason why it does not appear on GMAT.

However, what is the issue if they give rise to different values when the final answer is D? Is it conflicting with E, which states 'Statements (1) and (2) TOGETHER are NOT sufficient'?

I'm putting this question here because there is something wrong with it. It will never be on the GMAT. The challange here is to understand what's wrong, and why this won't be on the test.

The top of a ladder resting against a building is exactly 10 feet high from the base of a building. If the building is perpendicular to the ground, how far away from the building is the foot of the ladder?

1) The ladder is 20 feet long.

2) The foot of the ladder makes a 45 degree angle with the ground.

First figure out the answer and then figure out why it's not legit.
