70 70 7° We can make "pencilogons" by aligning multiple, identical pencils end-of-tip to start-of-tip together without leaving any gaps, as shown above, so that the enclosed area forms a regular polygon (the ample above left is an 8-pencilogon). Find the value of m + n. Hazri wants to make an n-pencilogon using n identical pencils with pencil tips of angle 7°. 18 8 pencils, he finds out the gap between the two ends is too small to fit in After he aligns n another pencil. So, in order to complete the pencilogon, he has to sharpen all the n pencils so that the angle of all the pencil tips becomes (7 — m)°. (Assume the pencils have a rectangular body and have their tips resembling isosceles triangles)
