Question

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

Answer 1

Step-by-step explanation:

angle DAC is inscribed in arc CD

angle CBD is inscribed in arc CD

therefore angle DAC = angle CBD

therefore angle CBD = x = angle B

In triangle CBD

angle B + angle C + angle D = 180

x + angle C + 2x = 180

3x + angle C = 180

angle c = 180 - 3x
