Question
given ( m parallel n ), find the value of ( x ).
answer attempt 1 out of 3
( x = )
Step1: Identificar ángulos suplementarios
Como \(m\parallel n\), los ángulos \(112^{\circ}\) y \((2x - 20)^{\circ}\) son suplementarios. Entonces \(112+(2x - 20)=180\).
Step2: Simplificar la ecuación
Simplificar \(112+(2x - 20)=180\) da \(2x+92 = 180\).
Step3: Resolver para \(x\)
Restar 92 de ambos lados: \(2x=180 - 92\), es decir \(2x = 88\). Luego dividir por 2: \(x=\frac{88}{2}\).
