    Given that 140° = kπ, find the exact value of k?
    Help appreciated, thank you in advance!

    rerrange to find k so k=140 divided by (pi)
    Soooo answer equals 44.6 to 1 d.p

    π radians is 180°.

    So formula becomes 140° = k x 180°

    Essentially, k = 140/180 = 7/9

    Just make RHS in degrees or LHS in radians

    I would say that 140 degrees is 7/18 of circle which in radians is 2π x 7/18 = 7π/9 radians. No need to memorise any formulas or anything.
