What does the ' mean by the numbers and can these be solved by a calculator?

It tells me to use a calculator to evaluate the value of the following trig functions but I don't know how to put the ' in a calculator.

7. sec 54° 23’

8. cos 36° 10’

9. cot 35° 21’ 45’’

sec 54° 23’

Most calculators have a way of putting in minutes and seconds.

BUT you have to change it to 1 / 54° 23’

The web 2 calc has the 'sec' function (trig) so you don't need to worry about that but it has no seconds(angle) function.

So you have to put it in like this

sec(54+23/60) = -1.7853120273505811

What kind of calc are you using?
