The line through (-2, 7) that is perpendicular to
5x + 10y = 8

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?

You can find the constant of proportionality by finding the ratio of

Equation for the calculation double 2 and then add 5
