What three notes (in solfege) make up the TONIC TRIAD in a major key?

The A major scale is A, B, C#, D, E, F#, G#. The second note is B, so that's the root of the supertonic ("above the tonic") triad. A triad built on B and using the above scale notes would come out as B, D, F# (remember that a third covers three note names, so B to D makes a third and D to F# makes another).
