I think b sorry if it’s wrong :(
Always because the sum of x and y is 180 degrees. If x and y are right angles, then x and y are supplementary angles. Never because the sum of x and y has to be 90 degrees. If x and y are complementary angles, then y is a right angle.
Answer:
3 gallons
Step-by-step explanation:
Length of the rectangular wall = 23.6 feet
Width of the rectangular wall = 19.2 feet
Surface area of the wall = 23.6 × 19.2
= 453.12 square feet
∵ 200 square feet of the wall is covered by the amount of paint = 1 gallon
∴ 1 square feet of the wall will be covered by the amount of paint =
gallons
∴ 453.12 square feet will require the amount of paint = 
= 2.2656 gallons
Therefore, minimum 3 gallons will be required to paint the wall.
Answer:
Two Angles that add up to 180
Step-by-step explanation:
90 degrees+ 90 degrees= 180 degrees
160degrees+ 20 degrees= 180 degrees
Hope this helps!
