Verified answer
Ángulo llano mide 180°
70° para 180°
[tex]180 - 70 = 110[/tex]
Sumamos y encontramos X
La suma total de los ángulos internos de un triángulo suman 180°
[tex]\large\boxed{\red{Respuesta=a)35}}[/tex]
[tex]110 + 35 + x = 180 \\ \\ 145 + x = 180x = 180 - 145 \\ \\ \large\boxed{\bold{Rpta \: x=35}}[/tex]
