ΔXYZ is right angled at Y. If m∠Z = 45°, then find the value of $$\left( {{\text{cosecX}} - \frac{2}{{\sqrt 3 }}} \right) = ?$$
Answer & Solution
Correct Answer:
Option
C
$$\eqalign{ & {\text{cosec X}} - \frac{2}{{\sqrt 3 }} \cr & = \frac{{\sqrt 2 x}}{x} - \frac{2}{{\sqrt 3 }} \cr & = \sqrt 2 - \frac{2}{{\sqrt 3 }} \cr & = \frac{{\sqrt 6 - 2}}{{\sqrt 3 }} \cr} $$
