Introduction to Chord LengthsINPlace the following expressions so that they can be used to solve for X11 781211 7.8 1211 INN111712

Answer 1

We know that the diameter of the circle is 18.8.

Therefore the value of its radius will be.

`(18.8)/(2)`

And we also know that the radius from the diagram is:

`x+4.2`

So we can equate both equations together to have an idea of what will give us the value of x.

`\begin{gathered} (18.8)/(2)=x+4.2 \\ \text{Collect like terms} \\ (18.8)/(2)-4.2=x \end{gathered}`

So going by the above solutions, the answers we will drag into the two boxes will be the 4th expression and the 6th expression

THAT IS:

`\begin{gathered} (18.8)/(2) \\ \text{and} \\ -4.2 \end{gathered}`
