Answer 1

Respuesta:

20°+y+50° = 180°

(20+50)°+y = 180°

70°+y = 180°

70°+y-70° = 180°-70°

y = 180°-70°

y = (180-70)°

y = 110°

y+3x+2x = 180° ; y = 110°

110°+3x+2x = 180°

110°+(3+2)x = 180°

110°+5x = 180°

5x = 180°-110°

5x = (180-110)°

5x = 70°

(5/5)x = 70°/5

x = 14°

Verificación :

(110°)+2(14°)+3(14°) = 180°

110°+14°(2+3) = 180°

110°+5(14°) = 180°

110°+70° = 180°

(110+70)° = 180°

180° = 180°

R// Por lo tanto , el valor de" x " es 14° .
