Answer:

3pi/4 =x       and 5pi/4 =x

Step-by-step explanation:

cos x + sqrt(2) = - cos x

subtract cos x from each side

cos x - cosx + sqrt(2) = - cos x - cos x

sqrt(2) = -2 cos x

Divide each side by -2

-sqrt(2) / 2 =-2 cos (x) /-2

-sqrt(2) /2 =cos (x)

Take the inverse cos of each side

cos(-1)(-sqrt(2) /2) =cos^-1(cos (x))

3pi/4 =x       and 5pi/4 =x

Answer: Ratio of black horses to all horses = 59/62

Step-by-step explanation:

Total number of horses = 62

Total number of white horses = 3

Assuming that the rest horses are black. That means the total number of black horses would be 62-3 =59. So there are 59 black horses and there are 3 white horses.

Ratio of black horses to all horses will be the total number of black horses / the total number of horses.

Ratio of black horses to all horses

= 59/62 or 59:62

It can also be expressed in decimals which will become

0.952
