at 2:10 is the first reading of vertical angle and first reading of horizontal angle , you use the reading at 4:21 for each and deduct from the first at 2:10 for each horizontal and vertical. the vertical angle means the height between point A and B vertically which is very low. which is around 94 - 86 = 8 degrees

What if the result was (- ve) ?
I. e the result after subtraction of the second from the first. 4:21
make it positive what you need is just the absolute difference without signs
