o find the radius of circle O, we can use the Pythagorean Theorem. Since BA is tangent to the circle at A, OA is perpendicular to BA. This means triangle OAB is a
Substituting the known values:
OA2 + 225 = 289
OA2 =
Thus, the radius of circle O is 8 units.
with OA as one leg, AB as the other leg, and OB as the
. Given that BA = 15 and OB = 17, we can find OA, the radius, using the equation:
Substituting the known values:
OA2 + 225 = 289
OA2 =
OA=8
Thus, the radius of circle O is 8 units.
