Answer 1

DESARROLLO:

$\alpha + 70 + 60 = 180 \\ \alpha + 130 = 180 \\ \alpha = 180 - 130 \\ \alpha = 50$

$\beta + 80 + 40 = 180 \\ \beta + 120 = 180 \\ \beta = 180 - 120 \\ \beta = 60$

$x + \alpha + \beta = 180 \\ x + 50 + 60 = 180 \\ x + 110 = 180 \\ x = 180 - 110 \\ x = 70$

RESPUESTA:

X = 70°
