Question 1197763
<font color=black size=3>
The polar form is {{{matrix(1,5,"(",r,",",theta,")")}}}
r = radius
theta = {{{theta}}} = angle


Useful formulas
{{{r = sqrt(x^2+y^2)}}}


{{{theta = arctan(y/x)}}}


In this case, the rectangular point we have is {{{matrix(1,9,"(",x,",",y,")=(",2,",",sqrt(3),")")}}}
which breaks down into {{{x = 2}}} and {{{y = sqrt(3)}}}

So,
{{{r = sqrt(x^2+y^2)}}}


{{{r = sqrt(2^2+(sqrt(3))^2)}}}


{{{r = sqrt(4+3)}}}


{{{r = sqrt(7)}}}
This is the distance from the origin (0,0) to the point {{{matrix(1,9,"(",x,",",y,")=(",2,",",sqrt(3),")")}}}


Unfortunately, none of the answer choices of the form {{{matrix(1,5,"(",r,",",theta,")")}}} have {{{r = sqrt(7)}}}. 
This means there's either a typo in the answer choices somewhere, or a typo in the given (x,y) rectangular coordinates.
