Use the figure below to find the length of AC . please help me .
Masja [62]

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.
