Question

Solve for x. G 7 H 5 J 6 K M

Answer 1

x = 4

Explanation:

given 2 secants from an external point to the circle, then the product of the measures of one secant's external part and that entire secant is equal to the product of the other secant's external part and that entire secant, that is

6(6 + x) = 5(5 + 7)

6(6 + x) = 5 × 12 = 60 ( divide both sides by 6 )

6 + x = 10 ( subtract 6 from both sides )

x = 4
