Answer:
AC = 146.2
Step-by-step explanation:
We are assuming that BC is tangent to circle A and that AB is perpendicular to BC. This problem involves the use of the Pythagorean theorem.
a = t
b = 25
c = 144
a² = b² + c²
a² = 25² + 144²
a = √(25² + 144²)
a = √625+20736)
a = √21361
a = 146.154
The length of AC is 146.2 units.
