It is given that one of the angles measure 44°. In a right triangle, one of the angles is guaranteed to be 90°. A triangle's total angle measurement is 180°. Set the equation:
Answer = Total measurements - (one angle + right angle)
It all depends upon what other things are given If hypotenuse is not given, in cosine or reciprocals are useless. In that case only tan and cot will be equally convenient if adjacent sides are given.
