                                (the semi-perimeter for the triangle), then the following all form the law of cotangents

                                We would go on to calculate the cotangent as 70 divided by 93 to get 3/4 or .75 and looking that up in a table of cotangents find that the angle of rise is a few minutes over 53 degrees.

                                In present day trigonometry, cotangents require the same units for run and rise (base and perpendicular), but the papyrus uses cubits for rise and palms for run, resulting in different (but still characteristic) numbers.
