1 and 17
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.
area = Pi*(radius squared) = 289*pi, or approximately 907.92 square units.
17 squared = 172 = 289
