Answer 2

Answer:

Step-by-step explanation:

so we know sin 0 is 1/3      

sin^2  0=1/9

sin^2 0 +cos ^2 0 =1         using identity sin^2 A+cos^2 A=1

we get cos ^2  0 as  1-1/9

which is

cos ^2 0 =8/9

cos 0 =root 8 /3

root 8 is 2 root 2

which implies   that     cos 0 is 2 root 2 /3

so  

we know cot 0   is

cos 0/sin 0

substituting values of sin and cos we get

2 root 2/3  the whole divided by 1/3

so we get cot 0 as 2 root 2

so we get

4 root 2+2

so we  get it as

2(2 root 2 +1)

2 root 2 is

2.828

so   we  get it as

3.828 *2

7.656
