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 ✔
Answer:
Step-by-step explanation:
3 consecutive integers : x, x + 1, x + 2
x + (x + 1) + (x + 2) = - 36...combine like terms
3x + 3 = -36...subtract 3 from both sides
3x = -36 - 3
3x = - 39....divide both sides by 3
x = -39/3
x = - 13
x + 1 = -13 + 1 = -12
x + 2 = -13 + 2 = -11
the largest integer would be -11
