Fill in the blank with the appropriate term.

an equation whose variables are polar coordinates is called a(n) equation.

I believe that the appropriate term to fill in the blank is "polar". An equation whose variables are polar coordinates is called a(n) polar equation. This type of equation are algebraic curves expressed in polar coordinates. Hope this answers the question. Have a nice day.

The ratio is 5:10 but when simplified it is 1:2 because you divide both numbers by 5
