Physics - electric field intesity (check +help)

posted by .

Points A and B are 13.0 apart. A charge of +8.0mu is placed at A and another charge at +5.0mu is placed at B. Point P i located 5.0cm from A and 12.0cm from B. What is the magnitude and direction of the electric field intensity at P?

Ans: i got the magnitude as 2.9*10^, however i cannot find the direction i keep getting 67deg, or 22deg. I tried substituting the electric field intensity however i do not get it, how do i find it?
