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
Answer:
Stated Below:
Step-by-step explanation:
x + y = 90 because the 2 angles add up to 90
.
Now, m < x = five times m < y, so x = 5y or y = x/5
So the last choice is the correct one.
