Answer 1

Ello user !!!!!!!!

Here is your answer,

========================================

Sin 89 = Cos (90 - 89)

            = Cos 1

========================================

HOPE THIS HELPS YOUU :)

AND STAY BLESSED.

Answer 2

Sin 89° = Cos ( 90° - 89° ) [ SinA = Cos (90-A)]

So Sin 89° = Cos 1°

Hence it is between 0° and 45° now
