Question 549183


The height bisects the base
Base = 10
so half the base = 5 cm
hypotenuse = 20

The congruent side the height and half the base will form a right triangle.
The congruent side is the hypotenuse.

height is the other leg

Pythagoras theorem						
						
(Hyp)^2= 		(leg1)^2+			Leg2^2	
Hypotenuse =			20	ft		
leg1=			5	ft		
Leg2=			?			
						
leg2^2=hyp^2-leg1^2						
Leg2^2= 		20	^2	-	5	^2
Leg2^2= 		400	-	25		
Leg2^2= 		375				
Leg2= 		{{{sqrt(175)}}}				
height=		19.36	ft
