Question

Are we supposed to be using sin? Actually, how do you even go about solving this problem?

Answer 1

Answer:

Step-by-step explanation:

let the distance between the center of small circle and the angle be x

$\frac{2}{x}$=$\frac{4}{x+2+4}$

                    2x+12=4x

                            x=6

∴sin($\frac{\alpha }{2}$)=$\frac{2}{6}$

        $\frac{\alpha }{2}$=19.47122063

                                               α=38.94244127
