We can calculate the length of AB using the Pythagorean Theorem, where:

So, replacing PA by 34 and PB by 16 and solving for AB, we get:

Then, AC = AB + BC, But AB = BC, so:
AC = 2*AB
Replacing AB by 30, we get:
AC = 2*30 = 60
Answer: AC=60
A line crossing the circle at point A and passing through its center O is perpendicular to a line tangent to the circle at point A.
Therefore, segment AB is perpendicular to OA. And segment BC is perpendicular to OC:
Yes, its quadratic. constant may be zero.
692.08 : 21.1
Divide both sides by 21.1
32.8 :1
