Dear student
 
As you have written show that but you have not provide one side that is to be proved.
Also Question is not clear root sign on which terms. So please insert an image or use brackets.
 
for the help, if cos theta = ½ and tan theta is positive then
 
theta is in 3rd quadrant.
hence theta = 240 degree
