Answer:
D
Step-by-step explanation:
- The Angle Sum Property of a Triangle states that the internal angles of a triangle add up to 180°
- Here, the sum is : 130 + 30 + 30 = 190°
- Therefore, the angle measurements are not correct
- The total angle measure of triangle should decrease by 10°
- By making the top angle 120°, the sum becomes 180°
- Hence, D is the correct option
