1) 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 measured with a change of 1 ° at most. MN interval was measured as x = 100m with a maximum error of 0.1%. What is the calculated height of the building, what is the error at the calculated height? For which measurement (x, β, θ) the calculated height is more sensitive, why?
