Question

Are the angle measurements in this triangle correct?

Answer 1

OD

In a triangle there is 180 degrees

Answer 2

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
