Question

value of x picture is given​

Answer 1

Step-by-step explanation:

Angles on substended by chod in circle at any point are equal

so,

Angle BDC = Angle CAB = 30°

Now,

In triangle BDC,

Angle BAC + Angel CAB + Angle BCD = 180°

70° + 30° + x = 180 °

100° + x = 180°

x = 180° - 100°

x = 80°
