Question

Find the value of 2 cot A + 3 cos A if sin a = root 3/2​

Answer 1

Answer:

If

$sin \: a = \sqrt{3} \div 2$

Then A must be = 60°

2 cot A + 3 cos A

$= 2 \times \frac{1}{ \sqrt{3} } + 3 \times \frac{1}{2} \\ = \frac{2}{ \sqrt{3} } + \frac{3}{2}$

Answer 2

Answer:

on rationalising the denominator is depend on u Or answer what is given in ur book.... if u do rationalisation it will be good... I hope you have understand.... mark my answer as brainlist and follow me....
