Answer:

540°

Step-by-step explanation:

Given that formula to calculate sum of interior angle of a regular pentagon

<h3> s = (n-2) * 180</h3>

<em>where n is number of side of a polygon which in this case is 5 because pentagon have 5 sides</em>

s =(5-2) * 180

s =(3)* 180

s =540°

A pentagon has 5 sides, and can be made from three triangles, so you know what its interior angles add up to 3 × 180° = 540°

Hope it helps you.

List the sides in ^ EFG in order from smallest to largest.
exis [7]
<h3>Answer: Choice A) EF, EG, FG</h3>

================================================

Explanation:

We'll use these two rules

  1. The smallest side is always opposite the smallest angle
  2. The largest side is always opposite the largest angle

This only applies to triangles.

EF is the smallest side because the angle G is the smallest angle.

FG is the longest side because it is opposite the largest angle E

That places EG in the middle.

The order of the sides from smallest to largest is EF, EG, FG

The sum of two numbers is x. If one of the numbers is 12, what is the other ?
Vlad1618 [11]
If the sum of two numbers is x

Then the equation is like this:

a+b = x

Then it says one of the number is 12. Change either a or b into 12

12 + b =x

If we want to find the other number, we need the make it into the subject

b = x - 12

Hope that help.
