What is dc if ac = 10 cm, bc = 6 cm, and ec = 12 cm? using the options below

To solve this question we will use a theorem called the intersecting secant theorem which states that "if 2 secants of a circle intersect outside the circle then product of their segments are equal".

Thus, applying this theorem in this question we see that:

Thus,

Thus,

Thus, out of the given options, the first option is the correct option.
