Question
question given m||n, find the value of x. answer attempt 1 out of 3 (4x + 15)° (9x + 9)°
Step1: Aplicar la propiedad de ángulos alternos internos
Como \( m\parallel n \), entonces \( 4x + 15=9x + 9 \)
Step2: Resolver la ecuación para \( x \)
Restar \( 4x \) de ambos lados: \( 15 = 5x+9 \)
Restar \( 9 \) de ambos lados: \( 6 = 5x \)
Dividir por \( 5 \): \( x=\frac{6}{5}=1.2 \)
