Answer:
cos 0=90 degrees
Step-by-step explanation:
If sin of 90 is 1 then cos 90 is 0. Since sin and cos are like complementary angles they angles add up to 90 degrees.

and since sin 90 equal 1 cos of 0 equal 1.
What if we switch angles
Well they are still equal

But this time sin of 0 is 0 and cos 90 is 0.
