Answer
$0.25, 2.89$
Work Step by Step
Step 1. $sin(\theta)=\frac{0.05}{0.2}=\frac{1}{4} \longrightarrow \theta=2k\pi+sin^{-1}(\frac{1}{4})$ and $\theta=2k\pi+\pi-sin^{-1}(\frac{1}{4})$
Step 2. Within $[0,2\pi)$, we have $\theta=sin^{-1}(\frac{1}{4})\approx0.25$ and $\theta=\pi-sin^{-1}(\frac{1}{4})\approx2.89$
