Answer:
7/8=0.875
0.875 x 100= 87.5

Step-by-step explanation:
To find the sum of the interior angles of a heptagon, divide it up into triangles ... There are five triangles... Because the sum of the angles of each triangle is 180 degrees... We get.
we know that 40 is the 100%, so what would 12 be off of it in percentage?
![\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 40&100\\ 12&x \end{array}\implies \cfrac{40}{12}=\cfrac{100}{x}\implies \cfrac{10}{3}=\cfrac{100}{x} \\\\\\ 10x=300\implies x=\cfrac{300}{10}\implies x=30](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Barray%7D%7Bccll%7D%20amount%26%5C%25%5C%5C%20%5Ccline%7B1-2%7D%2040%26100%5C%5C%2012%26x%20%5Cend%7Barray%7D%5Cimplies%20%5Ccfrac%7B40%7D%7B12%7D%3D%5Ccfrac%7B100%7D%7Bx%7D%5Cimplies%20%5Ccfrac%7B10%7D%7B3%7D%3D%5Ccfrac%7B100%7D%7Bx%7D%20%5C%5C%5C%5C%5C%5C%2010x%3D300%5Cimplies%20x%3D%5Ccfrac%7B300%7D%7B10%7D%5Cimplies%20x%3D30)
