Answer:
Step-by-step explanation:
The sides of a quadrilateral always add up to 360°.
Missing angle = 360-115-97-68 = 80°
Answer:
D. 80°
Step-by-step explanation:
A quadrilateral always add up to 360°
To find the missing value we first have to add the given number up:
115 + 97 + 68 = 280°
Now we minus our value from 360° :
360° - 280° = 80°
