Answer:
The answer is 0.28.
Step-by-step explanation:
We know that,
A trigonometric property is,
[tex]sin A = cos (90^{\circ} -A)[/tex]
Where A is any angle,
Given,
[tex]sin x = 0.28[/tex]
By the above property,
[tex]sin x = cos (90^{\circ}-x)[/tex]
[tex]\implies cos (90^{\circ}-x) = 0.28[/tex]
Hence, the answer would be 0.28.
