No, a triangle cannot have more than one obtuse angle. Obtuse angles are bigger than 90 degrees but smaller than 180 degrees. Pretend we had two obtuse angles both measuring 135 degrees and an acute angle measuring 23 degrees.
135 + 135 + 23 = 293
therefore, it wouldn't be a triangle anymore... a triangle only equals up to 180 degrees.
I hope that helps.
