ARC is

If ABC is an arc of a circle and /_ABC=135^(@), then the ratio of arc ABC to the circumference is :

In the figures, /_ABC is inscribed in arc ABC and intercepts arc AXC and /_BCD is inscribed in arc BCD and intercepts arc BYD. If /_ABC = 30^(@) and m ( arc BYD ) = 80^(@) then the m ( arc AXC ) = "…...." and measure of /_ BCD = "…........."
