Weldon bought a pair of hiking boots that cost $85.70 before tax. If an 8.5% tax is added to Weldon's total, how much did he spend in total on the hiking boots? Round to the nearest cent, if necessary.

In a certain pentagon, the interior angles are a,b,c,d,e where a,b,c,d,e are integers strictly less than 180. ("strictly less than 180" means they are "less than and not equal to" 180.) if the median of the interior angles is 61 and there is only one mode, then what are the degree measures of all five angles?
