Question

Under root 3 Cos A = 2 sin a find the value of cot a

Answer 1

Answer:

$cotA =\frac{2}{\sqrt{3}}$

and

A = 30°

Step-by-step explanation:

$\sqrt{3}cosA = 2sinA$

$\implies \frac{cosA}{sinA}=\frac{2}{\sqrt{3}}$

$\implies cotA=\frac{2}{\sqrt{3}}\\=cot 30\degree$

$\implies A = 30\degree$

Therefore,

$cotA =\frac{2}{\sqrt{3}}$

and

A = 30°

Answer 2

$\huge\sf{Answer:-}$

√3 cotA = 2sin A

= cotA / sinA = 2 / √3

= cotA = 2 / √3

= cot 30°

= A = 30°

So,

cotA = 2/√5 and A = 30° is the answer:-
