Expert Answer:

begin mathsize 16px style Given space that space angle AOB equals 130 degree
rightwards double arrow arc space AB equals 130 degree space space space space space space space space space space space space space space space space space central space angle
angle ACB equals fraction numerator arc space AB over denominator 2 end fraction space space space space space space space space space space space space space space space space space inscribed space angle space space space space space space space space space space
angle ACB equals fraction numerator 130 degree over denominator 2 end fraction equals 65 degree
angle ACB plus angle BCD equals 180 degree space space space space space space Straight space line space ACD
65 degree plus angle BCD equals 180 degree space
angle BCD equals 115 degree
angle BCD equals fraction numerator arc space BD over denominator 2 end fraction
115 degree equals fraction numerator arc space BD over denominator 2 end fraction
arc space BD equals 230 degree
Arc space BCD equals 360 degree minus 230 degree
Arc space BCD equals 130 degree
Arc space BCD equals angle BO apostrophe straight D equals straight a space space space space space space space space space space space space central space angle
Arc space BCD equals angle BO apostrophe straight D equals straight a equals 130 degree end style
