Answer:
see explanation
Step-by-step explanation:
In a parallelogram the opposite angles are congruent , then
2p - 50 = p + 10 ( subtract p from both sides )
p - 50 = 10 ( add 50 to both sides )
p = 60
Then
∠ E = ∠ I = p + 10 = 60 + 10 = 70°
-----------------------------------------------------
consecutive angles sum to 180° , so
∠ L = ∠ K = 180° - 70° = 110°
