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
Solve the rational equation by combining expressions and insulating the variable X .
all real numbers .
The answer for this answer would be B. X is less than -10 so B would be the answer.
