Question

If cot A= 12/5 , then the value of (sinA + cos A ) ×cosec A is :

Answer 1

Answer:

$\frac{17}{5}$

Step-by-step explanation:

$\cot(a) = \frac{12}{5} \\ ( \sin(a) + \cos(a) ) \csc(a) \\ 1 + \cot(a) \\ 1 + \frac{12}{5} \\ \frac{17}{5} \\ formula \: used \\ \sin(a) \csc(a) = 1 \\ cota = \frac{ \cos(a) }{ \sin(a) }$
