Input: = 90 Output: ABC = 45.00 degrees Input: = 65 Output: ABC = 32.50 degrees
- Let AC be an chord of a circle with centre O, and let C be any point on the circumference anywhere.
- Let, angle AOC(on center) is the given
*** QuickLaTeX cannot compile formula: *** Error message: Error: Nothing to show, formula is empty
- So angle should be on the circumference,
angle ABC = angle AOC/2
An angle at the circumference of a circle is the half angle at the centre subtended by the same chord.
Below is the implementation of the above approach:
The angle is 32.5 degrees
