RESOLVER :3?
RESOLVER : 3. (x + 2) = 81.
RESOLVER : 3. (x + 2) = 81.
En resumen
3(x + 2) = 81 3x + 6 = 81 3x = 81 - 6 3x = 75 x = 75 / 3 x = 25.

Respuesta : θ + β + 95 = 180 (θ + β = 85)2 2θ + 2β = 175 . (1) Ahora en la figura que tiene forma de pescadito α + 95 = 2β + 2θ α + 95 = 170 α = 170 - 95 α = 75 Explicación paso a paso :
