Question

Someone help me with this one :)

Answer 1

Respuesta:

Explicación paso a paso:

$\angle{3}=180^{\circ}-(69^{\circ}+47^{\circ}+31^{\circ})=33^{\circ}\\\\\angle{1}=180^{\circ}-(69^{\circ}+31^{\circ})=80^{\circ}\\\\\angle{1'}=180^{\circ}-\angle{1}=180^{\circ}-80^{\circ}=100^{\circ}\\\\\angle{2}=180^{\circ}-(45^{\circ}+\angle{1'})=180^{\circ}-(45^{\circ}+100^{\circ})=35^{\circ}\\\\\texttt{Por lo tanto:}\\m\angle{1}=80^{\circ}\,\,,m\angle{2}=35^{\circ}\,\,,m\angle{3}=33^{\circ}$
