So form a isosceles triangle with two sides 1429.25 and the remaining side equal to 60.
The vertex angle would then,

or in radians,

So then the arc length is

.
.
.
If we split the isosceles triangle into two equal right triangles, we can find the length of the other leg.

So then the rise, Z, is equal to this leg subtracted from the radius,
