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.

Answer:
40° and 140° (with x = -10)
Step-by-step explanation:
Since the angles are supplementary (when added, equal 180°), you can add the two angles together to get (-18x)°. 180/-18 = -10 for x. Fill in -10 for x in both expressions. (-14 • -10)= 140° and (-4 • -10)- 40°. 140+40=180
