Question

What is the length of chord An in Oo below?

Answer 1

Answer:

12 units

Step-by-step 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.
• $\therefore m(chord\:\overline{AN}) =m(chord\:\overline{ML})$
• $\because m(chord\:\overline{ML}) = 12\: units$
• $\therefore m(chord\:\overline{AN}) = 12\: units$
