write the question properly

Answer 2

Step-by-step explanation:

O is the centre of a circle and arc BCD subtends an angle of 140 at the centre O.

• TO FIND •

• Measure of remain angle at O

we know that the total angle on center of circle is 360°

so remaining angle = 360 - by arc BCD subtends an angle of 140

= 360 - 144

= 216
