Step 1: Start facing East
Step 2: Turn 100$^\circ$ clockwise
From East, 90$^\circ$ clockwise → South, plus 10$^\circ$ more → slightly East of South
New direction = 100$^\circ$ clockwise from East
Step 3: Turn 45$^\circ$ anticlockwise from current
Move 45$^\circ$ back from that position → ends up at South-East
So final direction = South-East
