Answer 2

Answer:

14.2 m

Step-by-step explanation:

see the attached solution, it is self explanatory

Girl moves from A to B to C, AC is the distance to be found

• AB=15 m, BC= 20 m, AC=?  
• AD=BD as  ∠DAB=45 deg  
• x²= AD²+CD²  
• CD²=(20-BD)²  
• AD²=15²/2  
• x²= 15²/2+(20-√15²/2)²  
• x²= 201  
• x=√201  
• x=14.2 m
