Answer:
A (acute), B (scalene)
Step-by-step explanation:
Every angle in the triangle is smaller than 90°, meaning that every angle is acute. If an angle is 90°, it is right, and if above 90° but below 270°, it is obtuse.
This triangle is scalene because none of the angles are the same. If two angles were the same, the triangle would be isosceles. If all the angles were the same (the only angles that satisfy this condition are 3 60°s), the triangle is equilateral.
