Answer 1

Answer:

hey your answer is as follows

so pls mark it as brainliest

Step-by-step explanation:

now here line cd is a tangent and cb is a secant

so angle bcd is inscribed in between of both of these

so by tangent secant angle theorem

we get angle bcd=1/2×m(arc bc) (1)

so moreover here angle cad intercepts arc bc on circumference of circle

thus by inscribed angle theorem

we get angle cab=1/2×m(arc bc) (2)

thus angle cab=angle bcd from (1) and (2)

so if we divide both of these angles we get the ratio as 1:1 because both of them are equal to each other

so thus option A is ryt ie ratio of angle bac:angle bcd=1:1
