[00:00:00]Can you find the angle X?

[00:00:04]Suppose the center of the circle is O.

[00:00:13]And if we join AO and BO then in any circle a radius and tangent they are perpendicular on each other.

[00:00:38]So OA it will be perpendicular on AP and OB it will be perpendicular on BP.

[00:00:55]And in AOBP it is a O B P this angle is 90° this angle is 90° this angle is 20° so this angle it will be 360° 90° 90° - 20° that will be 100 60° this angle is 160° and now in any circle any chord AB if it is making an angle theta at the center O then on the circle it will make an angle of theta divided by two.

[00:02:36]So angle ACB it will be angle AOB divided by two and angle ACB is X and angle AOB is 160° divided by two that will be 80° >> [music]
