Thnx for your help.

The statement is false because both sin80 is very close to sin90 (i.e., 1), while cos80 is very close to cos90 (i.e., 0). Now, as we all know a small positive number subtracted from a larger positive number always yeilds a positive number. So, sin80-cos80 is positive (i.e., >0).
To support this theory, there is the fact that both sin80 and cos80 lie in the first quadrant (about which you'll be learning in class 11th ).
Hope this helps.
