$(144.499, 1.488)$ $(144.499,1.488)$

To find $r^{2}$ $r^2$ , use Pythagorean theorem:

$12^{2} + 144^{2} = r^{2}$ $12^2+144^2=r^2$

$r = 144.499$ $r=144.499$

To find he angle, use tangent:

$tan θ = \frac{144}{12}$ $tan theta = 144/12$

$θ = 1.488$ $theta= 1.488$

Rewrite this in the form $(r, θ)$ $(r,theta)$

$(144.499, 1.488)$ $(144.499,1.488)$
