Given that tan xº = 3/7 ,find cos (90 - x)º giving the answer to 4 significant figures.

Answer 1

When you posted that before, you forgot to give us the value of tan xº
I had made up an arbitrary value to show how it was done.

Now that you have a value, surely you can put in those values instead
of the ones I used.
