1. The problem statement, all variables and given/known data
A bug is on one wall of a room. The lower left-hand corner of the wall is selected as the origin of a two-dimensional Cartesian coordinate system. The bug is located at the point having coordinates (1.8, .8) m

How far is it from the corner of the room?
What is it's location in polar coordinates?

r=?????
theta=????
2. Relevant equations

3. The attempt at a solution

Aren't these two question asking for the same thing? I need to use the pythagorean theorem right?

Thank you very much

The radius in the polar system is the distance - it also has a direction

Thank you very much

That makes sense, but aren't these two questions asking for the same thing?

Thank you

No, polar coordinates have both an angle and radius from origin.
