Converting complex number to polar form manually

[blackandyello]

i tried evaluating this http://www4a.wolframalpha.com/Calculate/MSP/MSP47881a005158fa72fi31000026df4f1iaf7g05e7?MSPStoreType=image/gif&s=49&w=109&h=39

and the correct answer r = 1.1147 and theta = 75.9


however, i tried to do it manually and ended with this

with different r and theta. any ideas?

tnx
