There are different kinds of angles. The measure of each exterior angle of the formation is 51.4.
<h3>What is a exterior angle in math?</h3>
The term exterior angle is known to be the angle that is found between a side of a polygon and that of an extended adjacent side.
The shape of the halftime is regular heptagon.
Note that a regular heptagon has 7 congruent sides and 7 congruent interior angles.
So the exterior angles are said to be congruent, based on the fact that angles supplementary to congruent angles are regarded as congruent.
So Let take n as the measure of each exterior angle.
7n = 360
n= 360/n
To Solve for n =51.4
Therefore, The measure of each exterior angle of the formation is 51.4.

The catalysts are the compound that are used in the chemical reaction for lowering the activation energy.
<h3>What are catalysts?</h3>
The catalysts are the compound that is used in the reaction to increase the rate of reaction. The catalyst is not used in the reaction.
The rate of reaction is increased with the addition of the catalyst-reactant adduct and the reduction in the activation energy of the reactant thereby aiding the formation of the product.
Thus, the catalyst is given as the compound that increases the rate of reaction by lowering the activation energy.

Answer:
Hello!
Explanation:
I understand why you might need help, but please email a teacher about this. You can get in major trouble if you are just to copy and paste. A naritive story is very fun to write! Narrative writing is writing that has a story, characters, conflict, and other essential parts of a story. Narrative writing is often synonymous with a story. And this differs greatly compared to other forms of writing, like in textbooks and certain nonfiction books. So for example, you can rewrite a fairy tale and make it modern! For example, take Snow White, but make it take place in a post-apociliptic world! Or maybe take Cinderella and make it a story about a spy. Hope this helped!
