Answer: 45° and 60°.
Explanation:
The sum of the angles that are in a triangle is 180°. If one of the angle of a triangle is 75°, the remaining angle will be:
= 180° - 75°
= 105°.
Since the other two angles are in the ratio of 3:4 and the remaining angle is 105°, the value of the angles will be:
= 3/(3+4) × 105°
= 3/7 × 105°
= 45°
= 4/(3+4) × 105°
= 4/7 × 105°
= 60°
Therefore, the remaining angles are 45° and 60°.
