\rm{(x+21)^\circ+(2x-45)^\circ+x^\circ=180^\circ\quad...\:Angle\:Sum\:Property\:In\:Triangle}

\longrightarrow\rm{x+21^\circ+2x-45^\circ+x=180^\circ}

\longrightarrow\rm{x+2x+x+21^\circ-45^\circ=180^\circ}

\longrightarrow\rm{4x-24^\circ=180^\circ}\longrightarrow\rm{4x-24^\circ+24^\circ=180^\circ+24^\circ}

\longrightarrow\rm{4x=204^\circ}\longrightarrow\rm{x=204^\circ/4=51^\circ}

\rm{\bigstar\:\:Now\:The\:Angles\:Are\:;}

\longrightarrow\rm{x=204^\circ/4=51^\circ}

\longrightarrow\rm{(x+21)^\circ=51^\circ+21^\circ=72^\circ}

\longrightarrow\rm{(2x-45)^\circ=2(51^\circ)-45^\circ=102^\circ-45^\circ=57^\circ}
