Answer 1

DESARROLLO:

$x + \alpha + θ = 180 \\ x = 180 - \alpha - θ$

Usaremos la formula del pescadito

$x + x = \alpha + θ \\ 2x = \alpha + θ \\ 2(180 - \alpha - θ) = \alpha + θ \\ 360- 2 \alpha - 2θ = \alpha + θ \\ 360 = \alpha + θ + 2 \alpha + 2θ \\ 360 = 3 \alpha + 3θ \\ 360 = 3( \alpha + θ) \\ \frac{360}{3} = \alpha + θ \\ 120 = \alpha + θ$

RESPUESTA:

$x + \alpha + θ = 180 \\ x + 120 = 180 \\ x = 180 - 120 \\ x = 60$
