In a

\Delta \,ABC

a = 13,\,\,b = 14

and

c = 15

, then reciprocals of

{r_1},\,\,{r_2}

and

{r_3}

are in the ratio

View answer and explanation

Correct option: C

8\;:7\;:6

Option B (

n\pi ,\;\,n\pi + \frac{\pi }{4}

) is correct because it is the general solution of the trigonometric equation derived from the given condition.
