Respuesta:
1) x = α-β
2) x = 36°
3) x = 38°
Explicación paso a paso:
1)
x = α-β
2)
3x + 10 + 2x - 10 = 180
5x = 180
x = 180/5
x = 36°
3)
x + 10 - (20 - 4x) = 180
x + 10 - 20 + 4x = 180
5x - 10 = 180
5x = 190
x = 190/5
x = 38°
(-b)+a=x
-b+a=x
3x+10+2x-10=180
5x=180
x=36
-(20-4x)+x+10=180
4x-20+x+10=180
5x-10=180
5x=190
x=38
