#(7pi)/4#

Explanation:

You can find the reference angle for the #theta# by calculating #tan^(-1)(|b/a|)#, which in this case would give #tan^(-1)(1)=pi/4#.

Knowing the reference angle we think about the quadrant in which the angle falls, which is QIV in this case. In QIV we find the actual angle by calculating #2pi-z#, where #z# is the reference angle. This give an angle of #(7pi)/4#.
