Question

Calcule o valor do x, y, z​

Answer 1

$x + {79}^{ \circ} = {180}^{ \circ} \\ \\ x = - {79}^{ \circ} + {180}^{ \circ} \\ \\ x = {101}^{ \circ}$

$z+ {67}^{ \circ} = {180}^{ \circ} \\ \\ z = - {67}^{ \circ} + {180}^{ \circ} \\ \\ z = {113}^{ \circ}$

$y + {79}^{ \circ} + {81}^{ \circ} + {113}^{ \circ} = {360}^{ \circ} \\ \\ y = - {273}^{ \circ} + {360}^{ \circ} \\ \\ y = {87}^{ \circ}$
