Tim

Looks like I am missing out anything

This is how I looked at it Angle Q splits into 45 and 45

So Angle AQS has Q and A as 45 and S as 90 this is one of the Triangle

And the other is QST which has Q as 45 and S at 90 and T at 45 again

Could you please explain

Tim I am stuck on this question.

Following your explanation - doesnt option 1 also give us the same result which is 1 when n = 0

If a and b are integers, and |a| > |b|, is a · |b| < a - b?

(1) a < 0

(2) ab 0

OA e

The official explanation is pretty long - and if was wondering if there are any tricks that can help in resolving the question in 2-3 minutes
