Question

What is the length of chord An in Oo below?

А
O A. 12 units
122
7.2 • 7.2
O B. 7.2 units
O C. 14.4 units
N
O D. 6 units

Answer 1

12 units

Explanation:

`In\: \odot O,`

• chords
  `\overline{ML}` and
  `\overline{AN}` are equidistant (7.2 units) from the center of the circle O.
• Measures of the chords equidistant from the center of the circle are equal.
• 
  `\therefore m(chord\:\overline{AN}) =m(chord\:\overline{ML})`
• 
  `\because m(chord\:\overline{ML}) = 12\: units`
• 
  `\therefore m(chord\:\overline{AN}) = 12\: units`
