Question 4 • FL-1206310-Geometry
A circle is shown. Secant A D and tangent E D intersect at point D outside of the circle. Secant A D intersects the circle at point B. The length of A B is a, the length of B D is 10, and the length of D E is 12.
Answer
A
12(a + 12) = 102B
10 + 12 = a2C
10(a + 10) = 122D
10(12) = a2
