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:

If this does not work,
then enter
