Simple math.

A -- offset angle
X -- horizontal offset at target
Y -- distance to target

Tangent A = X / Y

Also another simple rule is: "One degree angle is 17.5 yards per 1000 yards range."

So a two degree offset at 1000 yards will move the impact point 35 yards. Or a one degree over 1500 yards is 17.5 * 1.5 = 26.3 yards.
