Q1

Got to be careful because we cannot expand the brackets like we would for algebra.

Note that “without the use of calculators” simply mean that we should not find the angles A and B to solve this (since calculating each angle would require the use of calculators; no ordinary human can calculate this); it doesn’t mean that you cannot use calculators to help you simplify the fractions later on.
