    hi 321,
    Welcome to AAC.
    As this appears to be Homework, I will move it to the Homework Forum.

    You have an equation for Ri in terms of R1 and R2.

    You know Ri and you know R1.

    Solve the equation for R2.

    Show you work (best attempt) and we can help you through your difficulty.
