sine alpha = opposite/hypotenuse
alpha being angle subtended on periscope opposite = mast height hypotenuse = range so range = mastheight / sine angle subtended but the earlier scopes with the split prism had this calculation automated, as the american scopes do in sh4 Hitman fairly recently demonstrated that the telemetry markings on the periscope reticule were in radians rather than degrees, which apparently makes the range calculation easier
