What is the length of AC ? Enter your answer in the box. units Triangle A B C with vertical side A C. Vertex B lies to the right of side A C. Angle A and angle C are marked congruent. The length of side A C is labeled as x. The length of side A B is labeled as x plus 4. The length of side B C is labeled as 3 x minus 8.

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