 \: \: \boxed{\boxed{\rm{\mapsto Firstly \: Lets \: Understand}}}

\mathsf\red{☆ \: We \: know \: that \: sum \: of \: angles \: in \: a \: triangle \: = \: 180°}

\mathsf\red{Given}

\mathsf{Angles \: are \: in \: the \: ratio \: 1:2:3}

\mathsf{Let \: the \: angles \: be \: 1x , 2x , 3x}

\mathsf\red{then}

\mathsf{1x+2x+3x \: = \: 180°}

\mathsf{6x \: = \: 180°}

\mathsf{x \: = \: \frac{180}{6}}

\mathsf{x \: = \: 30}

\mathsf\red{\therefore \: the \: angles \: are \: :-}

\mathsf{1x \: = \: 30°}

\mathsf{2x \: = \: 2×30 \: = \: 60°}

\mathsf{3x \: = \: 3×30 \: = \: 90°}

\mathsf\red{The \: largest \: angle \: out \: of \: them \: is \:90°}
