Answer:
LENGTH OF AC IS 6
Step-by-step explanation:
Given :
the side AC = x ;
we need to find x;
since ∠A = ∠C , It's an isosceles triangle . i.e ,
the sides opposite to the angles ( AB and CB ) are also equal.
thus ,
side
AB = x+4 ;
CB = 3x-8 ;
thus AB = CB or ,
x+4 = 3x-8 ,
2x = 12 ,
x = 6 ;
therefore the side AC is 6.
