Question

m∠j = \square°
m∠k = \square°
m∠l = \square°

Explanation:

Step1: Find ∠E in △GFE

The sum of angles in a triangle is $180^\circ$.
$\angle E = 180^\circ - 50^\circ - 105^\circ = 25^\circ$

Step2: Match congruent triangle angles

Assuming $\triangle GFE \cong \triangle KLJ$ (corresponding vertices match the triangle shape):
$m\angle J = \angle E = 25^\circ$, $m\angle K = \angle G = 50^\circ$, $m\angle L = \angle F = 105^\circ$

Answer:

$m\angle J = 25^\circ$
$m\angle K = 50^\circ$
$m\angle L = 105^\circ$
