To determine the measure of angle J, we need to use the fact that the angles of similar triangles are corresponding angles and therefore, they are congruent.
Given that △BCE ∼ △JKL, we can conclude that:
m∠B = m∠J (corresponding angles)
m∠C = m∠K (corresponding angles)
m∠E = m∠L (corresponding angles)
From the given information, we know that m∠B = 89°. Therefore, m∠J = 89°.
