Assertion (A):If A=10^{\circ}, B=16^{\circ}, C=19^{\circ}, then \tan 2 {\A} \tan 2 {\B}+\tan 2 {\B} \tan 2 {\C}+\tan 2 {\C} \tan 2 {\A}=1 Reason (R): If {\A}+ {\B}+ {\C}=180^{\circ}, {\Cot} \frac{A}{2}+{\Cot} \frac{B}{2}+{\Cot} \frac{C}{2}={\Cot} \frac{A}{2} {\Cot} \frac{B}{2} {\Cot} \frac{C}{2} Which of the following is correct? [AP EAPCET 21 May 2024 Shift 2]

Correct Answer is : Both (A) and (R) are true and (R) is the correct explanation of (A)

Both ( {\A}) and ( {\R}) are true and ( {\R}) is the correct explanation of ( {\A})
