Question 870967
Two telephone poles are 60 meters apart.the poles are 42 metres and 69 metres high.


the difference between the lengths of poles = 27 m

the distance between them = 60 m

the poles are vertical

Apply Pythagorean Theorem

One leg				60	m				
Second leg				27	m				
Hypotenuse				x	m				
By Pythagoras theorem									
Hypotenuse^2 = Leg1^2+leg2^2									
{{{	x 	^2	=	60	^2	+	27	^2}}}	
x 	^2	=	3600	+	729				
x 	^2	=	4329						
{{{ sqrt(x^2)=		sqrt(	4329	)}}}					
x=	65.8	m							
the distance between their tops is 65.8 m
