Well: this might be some of it (and I like that they tell you what buttons to press):

Angle of slope represents the angle that’s formed between the run (remember it’s an idealized flat surface that ignores elevation change) and your climb’s angular deviation from that idealized flat surface. To calculate this, you divide the rise divided by the run, and then obtain the inverse tangent of the result.
Example: let’s assume your climb gains 1,000 feet in altitude (the rise) and the horizontal distance as measured on the map is 2,000 feet (the run).
1,000 divided by 2,000 equals .5
Press the INV button on your calculator (sometimes called 2nd function)
Press the TAN button on your calculator
Your angle of slope is 26.5 degrees [

At this point, though, one would need to fish out the measurements of the pyramid again, wouldn't one ...
