centre of circle,
find the value of x?
please attach a solution,8407008608 u can WhatsApp solution on this number. answer is not 100,if u get this answer then plz read the theorem u r using here properly​

Answer 1

Answer:

angle O = 2(30) = 60° ( angle subtended by an arc at the centre of a circle is double the angle subtended to any remaining part of circle or Theorem 10.8 )

20° + 60° + x = 180° ( Angle Sum Property )

or, 80° + x = 180°

or, x = 180° - 80°

or, x = 100°

The value of x is 100°.
