Narrative:

We were on final approach for runway 24R at lax following a 'heavy' boeing 777 with a light quarterly tailwind. The approach was stable until approximately 50ft when we believe we encountered the preceding 777's wake turbulence. The wake turbulence caused the left wing to suddenly raise; banking us to the right. At this time the egpws warning for 'bank angle' sounded. Captain called for the controls and I relinquished them. He corrected and landed in the touchdown zone.a suggestion that could have prevented this situation would be to touchdown beyond the preceding aircraft's touchdown point. In the future I will take caution whenever following a large aircraft with a tailwind and I will make a more immediate action to correct the situation or initiate an immediate go-around.
