Question
find the value of x for which ( l parallel m ). the angles given are alternate interior angles.
a. 20
b. 15
c. ( 36\frac{2}{3} )
d. 10
Step1: Igualar los ángulos alternos internos
Como \(l\parallel m\), entonces \(4x + 5=65\)
Step2: Resolver para \(x\)
Restar \(5\) de ambos lados: \(4x=65 - 5\)
\(4x=60\)
Dividir ambos lados por \(4\): \(x=\frac{60}{4}\)
\(x = 15\)
