Question

Solve for x
A. 12
B. 3
C. 2
D. 6

Answer 1

A

Explanation:

Using the intersecting secants theorem, the total length of each secant multiplied by the exterior segment of the secants are equal to each other.

Solving this as an equation:

`7(x-7+7) = 6(x-4+6)\\\\7x = 6(x+2)\\\\7x = 6x + 12\\\\x = 12`
