Answer:
4 pieces of chair rail are needed
Step-by-step explanation:
<u>Step 1: Calculate the perimeter of the room</u>
Perimeter of rectangle = 2L + 2B
Length = 18
Breadth = 14
Perimeter of room = 2(18) + 2(14)
Perimeter of room = 64 feet
<u>Step 2: Calculate the pieces of chair rail needed</u>
<em>Perimeter of room = 64 feet</em>
<em>Length of each chair rail = 16 feet</em>
<em>Total chair rails needed = Perimeter of room/length of each chair rail</em>
<em>Total chair rails needed = 64/16</em>
Total chair rails needed = 4
Therefore, Mr. Herzog needs 4 pieces of chair rails.
A vertical line is perpendicular to the x-axis because they would intersect to form a 90 degree angle.
Complementary angles add up to 90 degrees. Therefore, the answer is c. 18 + 72 = 90
One tenth is 0.1. Therefore, the answer has to be 2.x. Since 4 is less than 5, the 2 remains the same. The answer is 2.2.
