P,A,B,C are four points in order on a straight road that runs up a hillside and makes a constant angle of 10 degrees with the horizontal. A flagpole whose height is h meters stands at P. From A and B, the top of the flagpole has elevations of 30 degrees and 5 degrees respectively above the horizontal. If AB is 100m long, what is the height of the flagpole? If BC is also 100m long, what is the elevation of the top of the flagpole from C?
