Triangle JKL is isosceles. The measure of angle cap j is 72 degrees and the measure of angle cap k is 36 degrees Which statement describes angle cap l ?

The angles in a triangle add to 180°, so angle L = 180° − 72° − 36° = 72°. Since angles J and L are equal, they are the base angles of the isosceles triangle; angle K, at the vertex between the equal sides, is 36°. Therefore, angle L is a base angle measuring 72°.
