Complement adds to 90
complement of A is 90-A
supplement is adds to 180
supplemetn of A is 180-A
2(90-A) is -40+180-A
2(90-A)=-40+180-A
2(90-A)=140-A
distribute
180-2A=140-A
add 2A to both sides
180=140+A
minus 140 both sides
40=A
A=40 degres
Answer: The required equation be
Step-by-step explanation:
Since we have given that
Let the number of meeting rooms a hotel has be m

hello
we are going to solve this question via substitution method
put equation 2 into equation 1
put y = 11 into equation 1 or 2
with equation 1
put y = 11
fro the calculations above, the solutions to the equations with the value of x and y are (13) and (11)
