What is the value of d to the nearest tenth?

Step-by-step explanation:

A line that cuts a circle at two points is called "secant".

There is a theorem known as "Intersecting Secant Theorem". This is the theorem you need to use to find the value of "d".

According the Intersecting Secant Theorem:

Having this expression, the next step is to solve for "d":

Use Distributive property:

Subtract 256 from both sides:

Divide both sides by 16:

The value of "d" rounded to the nearest tenth is:
