Answer 2

Hey !!


★ Here is your answer ★


Let OX be the horizontal ground and let OB be the ladder leaning against the Wall AB.



Then, /_ AOB = 60° , OA = 9.5 m


And, /_ OAB = 90°.



Length of the ladder. = OB


Let OB = X m.


From right ∆OAB , we have :


OB/OA = Sec60° = 2




=> X/9.5 = 2




=> X = ( 2 × 9.5 )



=> X = 19 m .


Hence,


The length of the ladder is 19 m.
