1.	A tacheometer was placed at point P to estimate the horizontal distances PQ and PR. The corresponding stadia intercepts with the telescope kept horizontal are 0.320 and 0.210 m respectively. The ∠QPR is measured to be 61∘30′30′′ . If the stadia multiplication constant = 100 and stadia addition constant = 0.10 m. The horizontal distance (in m) between the points Q and R is____ 28.8
Answer» A tacheometer was placed at point P to estimate the horizontal distances PQ and PR. The corresponding stadia intercepts with the telescope kept horizontal are 0.320 and 0.210 m respectively. The $∠$ QPR is measured to be $61^{\circ} 30^{'} 30^{''}$ . If the stadia multiplication constant = 100 and stadia addition constant = 0.10 m. The horizontal distance (in m) between the points Q and R is____ 28.8
