Answer:
Regular polygons have all their angle the same. 90 degree angles can only make a square.
Explanation:
To be regular, all angles have to be congruent. That would be 7 right angles The sum of the angles for an n-sided polygon is (n-2)180 or when n=7 that is 5(180) which is 10(90). and you have only 7 times 90 if they were all 90.

Since the components in a mixture are NOT chemically bound, you cannot use chemical methods to separate them lest you’ll counter-intuitively mix them chemically to form compounds. Rather physical methods are used to separate the components.
Explanation:
Air is made of a mixture of gases like Nitrogen, Oxygen and Carbon dioxide and particles like dust particles and water vapor. It is a homogeneous mixture because the components are well mixed up proportionately through out the mixture. The different components air can be separated using their different densities or melting and boiling points.
