Find sinx given cos2x=5/9

Diano4ka-milaya [45]

Answer:

sinx = √2/3

Step-by-step explanation:

cos2x = 1-2sin²x

5/9 = 1-2sin²x

2sin²x =1-5/9

2sin²x = 4/9

sin²x = (4/9)/2

sin²x = (4/9)*(1/2)

sin²x = 2/9

sinx = √2/3

Mandarinka [93]

Answer:

The equation is 0.11x + 0.25 = 0.15x (I think) and the answer is 6.25 = x

Step-by-step explanation:

0.11x + 0.25 = 0.15x Subtract 0.11x from both sides

-0.11x -0.11x

0.25 = 0.04x Divide both sides by 0.04

6.25 = x
