Answer:
10 and 15
Explanation:
A quadrilateral will measure a total of 360 degrees. We already know that the measurements of other angles were 305 and 30. That's a total of 335 degrees. Subtract that from 360 to find out how many are left in the shape.
360 - 335 = 25. The other two angles are in a ratio 2:3. So you need to find numbers that add up to 25 in a ratio of 2:3
If you multiply that ratio by 5, you get 10:15. 10 and 15 add up to 25, so those are your other angles.
