Oiiii me ajudem
Porfavor ​

Answer 1

Ângulos alternos internos são iguais, logo :

$5\text x+8=7\text x-12$

$7\text x -5\text x = 8+12$

$2\text x = 20$

$\text x = 10$

ângulos :

$5\text x+8 = 5.10 + 8 \to \\{5\text x + 8 = 58 }$

$7\text x-12 = 7.10 -12 \\7\text x-12 = 70 -12 \\7\text x-12 = 58$

Somando :

$\huge\boxed{58+58 = 116 }\checkmark$
