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>
Answer:
First Option
Step-by-step explanation:
Parallel lines never intersect and are Parallel from each other
Answer: 
Step-by-step explanation:
Subtract 490 from both sides
Then flip
multiply both sides by
to cancel out 
Thus giving you -735 as your
.
Then you plug it back into the equation to solve.
