Hey !!!
sinx = 3/5 ( given )
We know a formula of cos2x = ( 1 - 2sin²x)
putting the value of sinx on value of cos2x = ( 1 - 2sin²x)
hence,
we get
cos2x = ( 1 - 2sin²x )
=> [1 - 2 × ( 3/5 )² ]
=> [ 1 - 2 × 9 /25 )
=> [ 25 - 18 /25 ]
=> 7/25 Answer ✔
N - the number
14 + n = 17 |subtract 14 from both sides
n = 3
The answer is C. you can check the attached picture.
