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 [tex]\beta[/tex] = 50° and the angle of the N point to the tower is [tex]\alpha[/tex] = 35, these angles are most often measured with a variation. MN interval was measured with a maximum error of 0.1% x = 100m.

1-What is the calculated height of the building, what is the error at the calculated height?

2-For which measurement (x, [tex]\beta[/tex], [tex]\alpha[/tex]) the calculated height is more

sensitive,

3-why?
