Answer:
a There are n-3 diagonals from each vertex.
b The diagonals from each vertex divide the polygon into n-2 triangles.
c In a regular polygon with n sides, each angle measures (n-2)180/n degrees.
Step-by-step explanation:
You can check to see which answers are true for a 3-sided or 4-sided regular polygon (a triangle or square).
triangle: 3 sides, 0 diagonals, 1 triangle 60-degree angles
square: 4 sides, 1 diagonal, 2 triangles, 90-degree angles
The statements that are true for our test cases are ...
a There are n-3 diagonals from each vertex.
b The diagonals from each vertex divide the polygon into n-2 triangles.
c In a regular polygon with n sides, each angle measures (n-2)180/n degrees.
Directions: Find the volume of each figure. Round to the nearest tenth if necessary.

A module house is made by sticking a triangular prism on top of a rectangular block, as shown in the diagram.
Answer:
d
Step-by-step explanation:
The volume of the triangular prism.
= Base area x length of the prism
The volume of the rectangular block.
= Length x width x height
The volume of the model house is 1260 cubic feet.
Option A is the correct answer.
What is a rectangle?
A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
We have,
Module house:
Triangular prism on top and a rectangular block.
The volume of the triangular prism.
= Base area x length of the prism
= (1/2 x 12 x 4) x 15
= 24 x 15
= 360 cubic feet
The volume of the rectangular block.
= Length x width x height
= 12 x 15 x 5
= 900 cubic feet
The volume of the block house.
= Volume of the triangular prism + Volume of the rectangular block
= 360 + 900
= 1260 cubic feet
Thus,
The volume of the model house is 1260 cubic feet.
Option A is the correct answer.

Find the height of a triangle whose base is 5 inches and area is 12 square inches.
Answer:
Therefore, Height = 4.8 inches.
Step-by-step explanation:
Given : A triangle whose base is 5 inches and area is 12 square inches.
To find : Find the height of a triangle.
Solution : we have given
Triangle base = 5 inches.
Area = 12 square in.
We need to find height of the triangle.
Area = * base * height .
Plugging the values .
12 = * 5 * height .
On multiplying both sides by 2
24 = 5 * height .
On dividing both sides by 5.
Height = 4.8 inches.
Therefore, Height = 4.8 inches.
Solve using substitution.

Which of the following is NOT equivalent to 78 ÷ 6? (72 + 6) ÷ 6 (72 ÷ 6) + (6 ÷ 6) (60 ÷ 6) + (18 ÷ 6) (72 ÷ 6) + 6
Answer:
(72 divided by 6) + 6
Step-by-step explanation:
78 divided by 6 is 13. The question (72 divided by 6) + 6 does not equal to 13, it equals to 14, therefore (72 divided by 6) + 6 is not equivalent.
Answer:
(72 divided by 6) + 6
