use your scientific calculator. if it's TI-like, 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)
