Respuesta :

m∠KLF + m∠BKL = 180° (definition of supplementary angles)

Also:

m∠KLF + m∠BKL = m∠BKL + m∠AKL(substitution property)

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

An angle is formed from the intersection of two or more lines. Types of angles are acute, obtuse and scalene.
