This is obtuse!
How I know?
Well, the triangle is more than 90 degrees, making it obtuse. If it was 90 degrees, it’d be considered a right angle. And if it’s less than 90 degrees, it’s acute.

Answer: Obtuse

This is because the lower left angle is larger than 90 degrees. This is assuming the triangle is drawn to scale (i.e. drawn accurately).

Any time there's an angle larger than 90, the triangle will be obtuse. If there's one angle exactly 90, then it's a right triangle. Otherwise, the triangle is acute (when all angles are smaller than 90).
