Question 67204: Two secants are drawn to a circle from an external point. The external secant length on the first secant is 12 and the internal segment length is 3X+1. The external secant length on the second secant is 15 and the internal segment length is 3X-1. Solve for x to determine the lengths of the two internal segments of the secants. Answer by cassiroberts(11) (Show Source):
You can put this solution on YOUR website! 12=3x+1
minus 1 from both sides to get 11=3x then you divide 3 from both sides to get x=11/3
15=3x-1
add 1 to both sides to get 14=3x then you divide 3 from both sides to get x=14/3
