Question

Pls need help asap

solve for x

thanks​

Answer 1

x=5

Explanation:

Use the tangent and secant formula:

`x^2=x(x+z)`

which states that the product of the lengths of the secant line + external segment equals the tangent line squared.

Substitute:

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

simplify

`36=16+4x`

subtract 16 from both sides

20=4x

divide both sides by 4

5=x

So, x=5.

Hope this helps! :)
