Narrative:
On the HLYWD1 arrival to lax we encountered turbulence; shortly after the aircraft began a roll to left more than 30 degrees of bank. I disconnected the autopilot upon realizing that we were likely experiencing wake and getting worse. I stayed above the glide path of the aircraft in front of us. The pilot monitoring inquired with ATC to see what type of aircraft we were following. Confirmation from ATC that we were following a boeing 777 approximately 8-8.5 miles ahead; the pilot monitoring asked if we can stay higher on the arrival due to a wake event with that aircraft. ATC gave us step down altitudes and eventually a runway change to remain clear of further wake. During the descent contact was made with both flight attendants and one flight attendant said she was injured. No passengers were injured; the captain handled further actions with coordination of the flight attendant injury and crew scheduling.
