Answer:


(\pi)/(4), \: (5\pi)/(4)

Explanation:


\sin(x).\tan(x) = \sin(x) \\ \\ \implies \tan(x) = (\sin(x) )/(\sin(x)) \\ \\ \implies \tan(x) = 1 \\ (\because\:0\leq x\leq 2\pi) \\\\ \implies \tan(x) = \tan (\pi)/(4) \: or \: \tan(x) = \tan \bigg(\pi + (\pi)/(4) \bigg) \\ \\ \implies x = (\pi)/(4) \: or \: x = (5\pi)/(4) \\ \\ \huge{\purple{x = (\pi)/(4), \: (5\pi)/(4)}}
