Hello :
<span>a single expression is : A = xy +zk
x : </span> width1 y : <span>length1
z : </span>width2 k : <span>length2
A : </span><span>the total area of the two rooms
note :
A1 = xy ........</span>area of the room 1<span>
A2 = zk </span>.......area of the room 2
X = 180 - (90 + 47)
x = 180 - 137
x = 43
answer angle x = 43
Answer:

Step-by-step explanation:
Given that x and y are proportional and the equation relating them is
y = rx ← r is the constant of proportionality
To find r use any ordered pair from the table
Using x = 9, y = 4.5 , then
4.5 = 9r ( divide both sides by 9 )
= r , that is
r =
