Verified Answer :

cos (90-x) x is 28. I hope this helps you.

Answer:

The answer is 0.28.

Step-by-step explanation:

We know that,

A trigonometric property is,

\(sin A = cos (90^{\circ} -A)\)

Where A is any angle,

Given,

\(sin x = 0.28\)

By the above property,

\(sin x = cos (90^{\circ}-x)\)

\(\implies cos (90^{\circ}-x) = 0.28\)

Hence, the answer would be 0.28.
