In Euclidean geometry, the base angles cannot be obtuse (greater than 90°) or right (equal to 90°) because their measures would sum to at least 180°, the total of all angles in any Euclidean triangle. Since a triangle is obtuse or right if and only if one of its angles is obtuse or right, respectively, an isosceles triangle is obtuse, right or acute if and only if its vertex angle is respectively obtuse, right or acute.
 Question: can the base angle of an isosceles triangle be obtuse Context: In baseball statistics, on-base percentage (OBP; sometimes referred to as on-base average/OBA, as the statistic is rarely presented as a true percentage) is a statistic generally measuring how frequently a batter reaches base. Specifically, it records the ratio of the batter's times-on-base (TOB) (the sum of hits, walks, and times hit by pitch) to their number of plate appearances. It first became an official MLB statistic in 1984.

The song was released first as a promotional single on November 8, 2015, and later was released as the album's third single. It was written by Ed Sheeran, Benny Blanco and Bieber, and produced by Blanco. An acoustic pop song, ``Love Yourself'' features an electric guitar and a brief flurry of trumpets as its main instrumentation. During the song, Bieber uses a husky tone in the lower registers. Lyrically, the song is a kiss-off to a narcissistic ex-lover who did the protagonist wrong.

This was partly due to the pressures of the World Hockey Association (WHA), but mostly the result of financial decisions made when the Salomons first acquired the franchise. Deferred contracts came due just as the Blues' performance began to slip. At one point, the Salomons cut the team's staff down to three employees. One of them was Emile Francis, who served as team president, general manager and head coach, who convinced then-chairman R. Hal Dean of the St. Louis-based pet food giant Ralston Purina to buy the team, arena and the 8.8 million dept. The Salomons followed suit as they sold the team to that company on July 27, 1977. However, Ralston said that this was only temporary until they found a stable owner in St. Louis. Ralston renamed the arena the ``Checkerdome.'' After two awful years including finishing with a franchise low 18--50--12 record with 48 points (still the worst season in franchise history) in 1979, the Blues made the playoffs the following year, the first of 25 consecutive postseason appearances.
