Determine each tangent ratio to four decimal places using a calculator.
A) tan 74 degrees
B) tan 45 degrees
C) tan 60 degrees
D) tan 89 degrees
How do I figure this out !?

use your scientific calculator. if it's TIlike, just make sure the rad/deg display shows deg
press 74
press tan
If you don't have one, there are online scientific calculators
On some of them you press tan first. 
on your calculator , find a key labeled DRG
press until DEG shows
I will do C), you follow the same steps for the others
press:
tan
60
=
you should get 1.732.....
If this does not work,
then enter
60
tan
=
(the last method is used by a small number of manufacturers)
