First, we work out the increase/decrease of the two amounts

There are 52-43 = 9 projects increase 

Percentage increase = \frac{number of increase}{original value}×100
Percentage increase = \frac{9}{43}×100
Percentage increase = 21% (to the nearest integer)

In regular polygons, if the number of sides, n, is odd, the lines of symmetry will pass through a vertex and the half of the opposite side.
Step-by-step explanation:
This is equivalent to say that a perpendicular bisector of a side of the regular polygon bisects the angle of the opposite vertex to the side, and divide the polygon into two symmetrical parts.
