In circle O, BC = 17 and DC = 30. The diagram is not drawn to scale.
1 answer:
Applying the secant-tangent theorem, the length of diameter, BA is: A. 52.9.
<h3>What is the Secant-Tangent Theorem?</h3>Considering the image given, the secant-tangent theorem states that:
DC² = (BC)(BA)
Given the following:
- BC = 17
- DC = 30
Substitute the values into the equation
30² = (17)(BA)
900/17 = BA
BA ≈ 52.9
Length of the diameter, BA is: A. 52.9
