Question

Solve for x help please

Answer 1

A. 5

Explanation:

Based on the secant and tangent theorem, (4 + x)*4 = 6²

We can solve for x using the equation which describes the relationship between secant and tangents.

Thus,

`(4 + x)*4 = 6^2`

`4*4 + x*4 = 36`

`16 + 4x = 36`

Subtract 16 from both sides

`4x = 36 - 16`

`4x = 20`

Divide both sides by 4

`(4x)/(4) = (20)/(4)`

`x = 5`
