Let the number be n.
Then 2(7-n) = 4n, or 14 - 2n = 4n, or 14 = 6n. Then n = 7/3 (answer)

Answer:
The sum of the interior angles of any polygon is (n-2)*180° (n being the number of sides) so for a triangle the sum of the interior angles is 180°. The sum of the interior and exterior angles is also 180°. To work out which sets are possible you subtract each number from 180° and then add all three answers together. If you get 180° then that set of numbers is possible. Using this method, you will find that the following sets can be the measures of the exterior angles of a triangle:
its
120°, 120°, 120°
Answer:
1: 80% is 4/5 of the whole quantity
2: 1/5 is 20% of the whole quantity
3: 50% is 1/2 of the whole quantity
4: 1 is 100% of the whole quantity.
