1 and 17
Roughly close to something near 289.
If it were, then 17 squared would equal 8 squared plus 15 squared. ie 289 would equal 64 + 225 which it does, so it is a pythagorean triangle.
If a = 17 and a x a = 289 then no other values of a can exist.
Sin squared is equal to 1 - cos squared.
17 squared = 172 = 289
3 squared is equal to 9
