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.

<em>60 ; 100</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>HCF = 20 = 4×5 = 2²×5</em>
<em>LCM = 300 = 3×100 = 3×4×25 = 2²×3×5²</em>
<em>LCM/HCF = 2²×3×5²/2²×5 = 3×5</em>
<em>a = 3×hcf = 3×20 = 60</em>
<em>b = 5×lcm = 5×20 = 100</em>
<em>Good luck !</em>
