There is a way to do so using Degrees via the Sine and Cosine functions.
local degree = 180 --the degree you want
local magnitude = 5 --how big it is (also goes negative)

local calcx, calcy = math.sin(degree) * magnitude, math.cos(degree) * magnitude

Same but with a function:
function getrotationvalue(deg, mag)
    local degree = deg
    local magnitude = mag

    local calcx, calcy = math.sin(degree) * magnitude, math.cos(degree) * magnitude
    return calcx, calcy
end

Hope this helps understading this issue you're having!
