Answer:
54°, 90°, 108°, 126°, 162°
Step-by-step explanation:
The sum of angles in a pentagon is 180°(5 -2) = 540°.
The sum of ratio units is 3 +5 +6 +7 +9 = 30. So, each "ratio unit" stands for ...
540°/30 = 18°
Then the angles are found by multiplying the given ratios by 18°:
3 : 5 : 6 : 7 : 9 = 54° : 90° : 108° : 126° : 162°
