yes they can and it would be an acute triangle.
circumradius | 44/sqrt(39)~~7.04564
inradius | sqrt(39)/2~~3.1225
area | (35 sqrt(39))/4~~54.6437
perimeter | 35
interior angles | ((180 cos^(-1)(31/44))/pi° | (180 cos^(-1)(5/8))/pi° | (180 cos^(-1)(5/44))/pi°)~~(0.789014 radians | 0.895665 radians | 1.45691 radians)
interior angle sum | 180° = pi rad
exterior angle sum | 900° = 5 pi rad
