How do I convert this to rectangular form? I know Euler's formula is how we are going to convert the complex number to a rectangular coordinate. Where i'm confused is r being 1.6. Any help would be great!

$$z=1.6\angle\frac\pi6=1.6\left(\cos\frac\pi6+i\sin\frac\pi6\right)=\frac45\sqrt{3}+\frac45i.$$
