Am I missing something?

By definition of a triangle's altitude, h_a would be perpendicular to side a.  This would mean, in accordance to Pythagoras, that
a1 = SQRT((75)2 - (60))2) and a2 = SQRT((100))2 - (60))2), where a = a1 + a2.  Thus a1 and a2 equals 45 and 80, respectively, which means side a should equal 125, not 35.
