What is k equal to in the equation r=k/(k-5)

i dont know if my answer is correct but this is probably your answer

Step-by-step explanation:

The equilibrium expression is the reciprocal of that given. If the coefficients in a balanced equation are multiplied by a factor, n, the equilibrium expression is raised to the nth power. K' is the constant for the reaction multiplied by n and K is the constant of the original reaction.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

sine
