Answer:
40°, 80°, 120°, 120°
Step-by-step explanation:
sum the parts of the ratio, 1 + 2 + 3 + 3 = 9 parts
The sum of the interior angles of a quadrilateral is 360°
Divide this by 9 to find the value of one part of the ratio.
360° ÷ 9 = 40° ← value of 1 part of the ratio
Then
2 parts = 2 × 40° = 80°
3 parts = 3 × 40° = 120°
The 4 angles are 40°, 80°, 120°, 120°
