Integer triangle not) satisfy formula_151. We can generate the full equivalence class of similar triangles that satisfy B=3A by using the formulas where formula_28 and formula_27 are integers such that formula_157. Note that all triangles with B = 3A (whether with integer sides or not) satisfy formula_158. The only integer triangle with three rational angles (rational numbers of degrees, or equivalently rational fractions of a full turn) is the equilateral triangle. This is because integer sides imply three rational cosines by the law of cosines, and by Niven's theorem a rational cosine coincides with a rational angle if and only if the
The Three Degrees Kenny Gamble and Leon Huff, where they had their greatest successes. The first song they recorded for the label was with the studio band MFSB, titled "TSOP (The Sound of Philadelphia)", which was the theme song for "Soul Train". In October 1973, the group also made an appearance on the American television sitcom "Sanford and Son" (season 3, episode 4), singing their song "I Didn't Know". Their first album for the Philadelphia International label, "The Three Degrees", spawned three hits: "Dirty Ol' Man" (which went gold in the Netherlands and Belgium), "Year Of Decision" (which made it to #13 in
