Answer:
Step-by-step explanation:
see in this diagram angle A is 120 and the line from center O will make it two equal angle..this can be proved by CPCT.
then u can go with the relation of Cos=perpendicular/base
since radius is given so put it as the perpendicular and base will be length of tangent and value of cos 60=root3/2
as tangent are at right angles
sorry for poor quality diagram
