A triangle has two sides measuring 20 yards and one side measuring 19 yards. What kind of triangle is it?

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?

In the diagram below, tan θ = sqrt 3. what is the value of m?
