Question

if casA=root 3 by 2 ,then the value of cot a
is?​

Answer 1

Step-by-step explanation:

$cos \: A = \frac{ \sqrt{3} }{2} \\ \implies \: cos \: A = cos \: 30 \degree \\ \implies \: A = 30 \degree \\ \therefore \: sin \: A = sin \: 30 \degree \: = \frac{1}{2} \\ cot \: A = \frac{cos \: A }{sin \: A } = \frac{ \frac{ \sqrt{3} }{2} }{ \frac{1}{2} } = \frac{ \sqrt{3} }{2} \times \frac{2}{1} \\ = \sqrt{3}$
