54°, 54°, and 72°; acute triangle
36°, 36°, and 108°; scalene triangle
36°, 36°, and 108°; obtuse triangle

Answer:

B

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180°

sum the parts of the ratio 3 + 3 + 4 = 10 parts

divide 180° by 10 to find one part of the ratio

[tex]\frac{180}{10}[/tex] = 18° ← 1 part of the ratio

3 parts = 3 × 18° = 54°

4 parts = 4 × 18° = 72°

thus the 3 angles are 54°, 54° and 72°

All 3 angles are acute angles

Hence an acute angled triangle
