Hypotenusal allowance is given by the expression (adopting standard conventions)

(cosθ -1) × measured distance

(1 – secθ) × measured distance

(1- cosθ) × measured distance

(secθ - 1) × measured distance

(cosθ -1) × measured distance

In a survey work, three independent angles X, Y and Z were observed with weights WX, WY, WZ, respectively. The weight of the sum of angles X, Y and Z is given by:

\(\left( {\frac{1}{{{W_X}}} + \frac{1}{{{W_Y}}} + \frac{1}{{{W_Z}}}} \right)\)

\(\frac{1}{{\left( {\frac{1}{{{W_X}}} + \frac{1}{{{W_Y}}} + \frac{1}{{{W_Z}}}} \right)}}\)

\(\left( {\frac{1}{{{W_X}}} + \frac{1}{{{W_Y}}} + \frac{1}{{{W_Z}}}} \right)\)
