Join the centre O to the chord (let it be MN) & let OH be the perpendicular to the chord
OH bisects MN into 2 equal parts (each one is x/2)
OMH is a right triangle with one side =8, the second leg =x/2 & the hypotenuse = 12 (Radius)
Apply Pythagoras:
12² = 8² +(x/2)² ==>144=64 + x²/4 ==> x²=4(144-64) =320
x²=320==> x=√320 =17.88 ≈17.9
29). The 'six' is the same as (6 x 5) = 30 fifths.
So six and three fifths = (30 + 3) fifths = thirty-three fifths.
30). The 'eight' is the same as (8 x 6) = 48 sixths.
So eight and five sixths = (48 + 5) fifths= fifty-three sixths.
31). Twenty-seven of the thirds are the same as (27/9) = 3 .
That leaves a remainder of 2 thirds.
So twenty-nine thirds are the same as 3 and 2/3 .
32). Thirty-two of the fourths are the same as (32/4) = 8 .
That leaves a remainder of one fourth.
So thirty-three fourths are the same as 4 and 1/4 .
