Radius X Chord

Radius X Chord

J Dunn 2021

When a radius intersects a chord at a right angle, it bisects the chord. X = 6

All radii are equal. Since d = 31.8, r = 15.9 -- meaning x = 15.9 - 7 = 8.9

Sometimes you have to use Pythagorean Theorem. Remember - all radii are equal

An alternative would be to say that the left side of the chord is also 10.6 and pythagorean w/ the left-hand triangle
