A surveyor counted $90,88,91,93,93,89,$ and $91$ paces in seven trials of walking

along a $200-$ft known length on level ground. Then $86,83,84,87,$ and $85$ paces

were counted in walking five repetitions of an unknown distance $AB.$

a$)$ What is the pace length of the surveyor?

b$)$ What is the lenath of $AB?$

Work:

A slope distance $AB$ is measured as $211\mathrm{.}12$ ft$..$ The slope angle was $3{25}^{\text{'}}54"\text{'}.$

Compute the horizontal distance between point A and $B.$
