A transit with stadia interval factor of 100.8 was set up at point C on the line between points A and B. The following readings were observed: HAIR READINGS ROD VERTICAL ANGLE UPPER MIDDLE LOWER A +15-25 1.972 1.854 1.732 В -09-07 1.330 1.175 1.010 If the distance from the instrument to the focus is 0.38m, determine the following: a) Horizontal distance between A and B. b) Difference in elevation between A and B.

Locate the centroid x̄ of the shaded area.
