Step-by-step explanation:

Given that:

दी गई आकृति में 0 वृत्त का केन्द्र है। यदि angle BOD = 124° हो, तो angle x का मान ज्ञात कीजिए

To find:

 \angle \: x

Solution:

BD is a chord,which subtends 124° angle on the center of circle

Other angle at O is

360°-124°=236°

As shown in attachment.

Thus,

 \angle \: BCD =  \frac{236}{2}  \\  \\ \bold{ \angle \: BCD= 118°} \\  \\

[If a chord subtends theta angle at center of circle,then it subtends half of theta in the remaining part of center]

Now,

BCE is a line.

Sum of all angles on a straight line is 180°

\angle \: BCD + \angle \: x = 180° \\  \\ 118° + \angle \: x = 180° \\  \\ \angle \: x = 180° - 118° \\  \\ \angle \: x = 62° \\  \\

Thus,

\bold{\angle \: x = 62°} \\  \\

Hope it helps you.
