You can put this solution on YOUR website! The triangle is both acute and oblique.
Obtuse triangles have an angle that is greater than 90 degrees, which the triangle described does not.
Acute triangles have all their angles under 90 degrees, which our triangle does.
Oblique triangles are all triangles that do not have a 90 degree angle. Since our triangle does not have a 90 degree angle, it is oblique.
