Which equation results from applying the secant and tangent segment theorem to the figure? 12(a + 12) = 102 10 + 12 = a2 10(a + 10) = 122 10(12) = a2
THIS IS THE BEST ANSWER 👇
1. You must apply the Secant and Tangent segment theorem, which establishes:
Tangent² = (Total secant segment) (External secant segment)
2. The total secant segment is: AD = a + 12
3. The outer secant segment is: BD = 10
4. The tangent segment is: DE = 12
5. Then you must:
DE² = ADxBD
12² = (a + 10) 10
10 (a + 10) = 12²
6. Therefore, the third choice is the answer: 10 (a + 10) = 12²
