# 2 60, 58 , 62 #3 10,80,90
Explicación paso a paso:
2x+2 + 2x +2x + 4 = 180
6x + 6 = 180
6x = 180 - 6
6x = 174
x= 174/6
x =29
2x+ 2 = 2(29)+ 2 = 60
2x = 2(29) = 58
2x+ 4 = 2(29) + 4 = 62
Pregunta 3
x + 8x + 90 = 180
9x = 180 -90
9x = 90
x = 90/9
x= 10
Angulo x = 10
Angulo 8x = 8(10) = 80
Angulo recto = 90
