Drew picture not shown here, distance from center to the chord, . See a right triangle, hypotenuse 12 same as radius, leg 10 units.
An angle measure betwen the described distance and the hypotenuse, ; and you want TWICE this angle: 112.88 degrees.
The major arc is 247.11 degrees. Answer by MathTherapy(10552) (Show Source): You can put this solution on YOUR website!
