Answer:
There's no question attached to this statement
Length AC is 12 .
<u>Step-by-step explanation:</u>
We have , △ABC is inscribed in a circle such that vertices A and B lie on a diameter of the circle. If the length of the diameter of the circle is 13 and the length of chord BC is 5 . According to the data given in question we can visualize that triangle must be a right angled triangle where:
AB = hypotenuse = 13
BC = base = 5
Ac = Perpendicular
Now, By Pythagoras Theorem:
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
∴ Length AC is 12 .
