In Nebraska, servers need to be at least 19 years of age in order to sell and serve alcohol, but only 16 to handle and dispose of alcohol containers. This means a 19-year-old can bartend and a 16 year-old-can haul full and empty liquors bottles to and from a Nebraska bar.
A triangle with one interior angle measuring more than 90Â° is an obtuse triangle or obtuse-angled triangle. If c is the length of the longest side, then a2 + b2 < c2, where a and b are the lengths of the other sides. A triangle with an interior angle of 180Â° (and collinear vertices) is degenerate.
Acute and obtuse triangles. An acute triangle is a triangle with all three angles acute (less than 90Â°). An obtuse triangle is one with one obtuse angle (greater than 90Â°) and two acute angles. Since a triangle's angles must sum to 180Â°, no triangle can have more than one obtuse angle.
