Answer:
x = 2
Explanation:
This is referred to as the secant- secant theorem
When 2 secants are drawn from an external point to a circle, then the following equation exists
outside × whole = outside × whole
4(4 + x) = 3(3 + 5)
16 + 4x = 24 ( subtract 16 from both sides )
4x = 8 ( divide both sides by 4 )
x = 2
