On a scientific calculator, there will normally be a small indicator on the display saying whether it is operating in degrees, grads or radians. The key to change this setting if necessary will probably be MODE. (Look in the instruction book for the particular calculator).

You then key in either:
1.2799 [tan^(-1)] or [tan^(-1)] 1.2799.
Again it depends on the make and model.

In a 4-figure trig. table, look down the values in the left hand column of tangent values until you find the required value. Read the degrees (52) from the leftmost column printed in bold, and the minutes (0) from the top of the column.

C) 52 degrees

On your calculator (make sure it's on degrees mode) put in 1.2799, then push tan^-1 (probably shift + tan).

Draw a unit circle on a very large piece of graph paper. Use a protractor to measure the angle, then use the trig definitions and a ruler.
