Question

In the given figure,
is the centre of the circle. Find the value of x​

Answer 1

X=30°

since ang.X = ang.B,

bcz... they are the angles subtended by the same chord

in ∆BDC,

ang[A + B + C] = 180°{angle sum prp.}

X + 2X + 90° = 180°

{angle c is subtended by simicircle, so it is a right angle}

3X = 90°

•°• X = 30°

thank you

hope it helps you.....
