2) Radius of a cricket with centre P is 5 cm. If the point Q is such that degree Own=6 cm where does the point Q lie?
3) □ABCD is a cyclic quadrilateral if /_ A=83° find measure of the angle C. 4)TANGENT NCAA touches the circle at the point A,of Ad is a chord such that m ( arc Ad)=100° then find measure of the /_ CAD

Answer 1

ummmmm use the theorem:
    radius is perpendicular to a chord on its circumference
