It is: 180(n-2)
For example, the sum of the interior angles of a triangle is 180 degrees.
The quadrilateral can be cut into two triangle so the sum of the interior angles of a quadrilateral is 180*2=180*(4-2)
The pentagon can be cut into three triangle so the sum of the interior angles of a pentagon is: 180*3=180*(5-2)
The hexagon can be cut into four triangle so the sum of the interior angles of a hexagon is: 180*4=180*(6-2)
Answer:

Answer:
Moses got into the elevator at the 8th floor.
Step-by-step explanation:
Let's call the floor which Moses started at x. Going down decreases the floor number and going up increases the floor number. We then form the equation 
which is the same as 
which means 
. Moses got in at the 8th floor.
Answer:
You would explain what I did in the step by step explanation.
Step-by-step explanation:
There are three types of triangles: equilateral, isosceles, and scalene. An equilateral triangle has all 3 sides congruent, an isosceles has only 2 sides congruent, and a scalene has no sides congruent. So, if the triangle has marked sides congruent, or you have found some sides congruent, then you look at the amount of sides congruent, and then you can find the type of triangle. For example, if you have a triangle called ABC, and AB and BC are congruent but AC is not, then it is Isosceles because 2 sides are congruent. You would explain the 3 triangle definitions to your friend.
