Answer 1

`x = 4.1`

Step-by-step explanation

The line segment connecting the center and the chord bisects the chord.

Half of the length of this chord forms one of the shorter legs of the right triangle.

`= (15.6)/(2) = 7.8`

We use the Pythagoras Theorem to obtain;

`{x}^(2) + {7.8}^(2) = {8.8}^(2)`

`{x}^(2) = {8.8}^(2) - {7.8}^(2)`

`{x}^(2) = 16.6`

`x = √(16.6)`

`x = 4.1`
