If xsin60°.tan30° = sec60°.cot45° , then the value of x is?
Answer & Solution
Correct Answer:
Option
C
$$\eqalign{
& x\sin {60^ \circ }.\tan {30^ \circ } = \sec {60^ \circ }.\cot {45^ \circ } \cr
& {\text{Put values }} \cr
& \Rightarrow x.\frac{{\sqrt 3 }}{2}.\frac{1}{{\sqrt 3 }} = 2.1 \cr
& \Rightarrow \frac{x}{2} = 2 \cr
& \Rightarrow x = 4 \cr} $$
