Please use a calculator to change the rectangular coordinates (-2.5,7) to polar form. Round r and θ to 3 decimal places and let -180° < θ < 180°.
============================
Do it like this one:
----------
Please use a calculator to change -0.135 + 1.67i to polar form. Round r and θ to 3 decimal places and let –л < θ ≤ л.
---------------
r =~ 1.657
----
Angle = atan(1.67/-0.135)
Angle =~ 94.622 degs
