Question 544918
The ladder,the floor & the wall form a right triangle.									
The base is one leg	The height is the other leg				
The ladder acts as the hypotenuse									
Pythagoras theorem									
									
(Hyp)^2= (leg1)^2+Leg2^2				

One leg				35	ft			
Second leg				25	ft			
Hypotenuse 				x 	ft			
By Pythagoras theorem 								
Hypotenuse^2 = Leg1^2+leg2^2								
{{{ 	x 	^2	=	35	^2	+	25	^2}}}
x 	^2	=	1225	+	625			
x 	^2	=	1850					
{{{ sqrt(x^2)=		sqrt(	1850	)}}}				
x=	43	ft	length of ladder
