Question
the lines a and b are parallel. what is the value of x based on the following angles?
draw
(8x + 120)°
a
b
(-2x + 70)°
Step1: Aplicar la propiedad de ángulos consecutivos internos
Los ángulos consecutivos internos entre líneas paralelas suman \(180^{\circ}\). Entonces, \((8x + 120)+(-2x + 70)=180\).
Step2: Simplificar la ecuación
Combinar términos semejantes: \(8x-2x+120 + 70=180\), es decir \(6x+190 = 180\).
Step3: Resolver para \(x\)
Restar \(190\) de ambos lados: \(6x=180 - 190=-10\). Luego dividir por \(6\): \(x=\frac{-10}{6}=-\frac{5}{3}\).
