How do you calculate #cos^-1 (2.3/5.4)#?
64.8°
This is the value of the Cos of our known angle. To find the angle you either need to use a calculator or a table.
Do the calculation on a calculator, then press 2nd function/shift and Cos. Some calculators need the = sign pressed, others will give tha answer immediately.
You can also key it in as: shift cos (2.3÷5.4) =
