CAN SOMEONE EXPLAIN AND MAYBE SHOW ME STEP BY STEP WHY THE ANSWER IS 75degrees. HURRY 50 points and brainiest!!!

Answer:
75 degrees, we know that already so look below lol.
Step-by-step explanation:
This triangle is an isosceles triangle, LP is equivalent to LQ, and angles LQP and LPQ are also equivalent. We understand that PLQ is equal to 30 degrees, since its complementary to triangle LQM.
180 - 30 = 150
150/2 = 75.
Have a nice day, fam. Spread The Love. Thanks for the opportunity.
