The height of a tower is measured at the angle of two different points in the same direction on the ground. The angle of the M point to the tower is β = 50 ° and the angle of the N point to the tower is ϑ = 35 °, these angles are most often measured with a variation. MN interval was measured with a maximum error of 0.1% x = 100m. What is the calculated height of the building,...
