Given
∠MQL = 180° and ∠XQR = 180°
Find out which equation be used to solve problems involving the relationships between ∠XQL and ∠MQR.
To proof
Vertically opposite angle
The angles opposite each other when two lines cross. They are always equal.
As shown in the diagram
∠XQL, ∠MQR are vertically opposite angle.
∠XQL = ∠MQR
(48 +1b) = (54 - 1b)
The problem used to solve problems involving the relationships between ∠XQL and ∠MQR is (48 +1b) = (54 - 1b).
option ( A) is correct.
Hence proved

First Let we solve the Original system of equations:
equation (1): 
equation (2): 
Multiplying equation (1) by 7, we get
Subtracting,
implies 
Then
Thus the solution of the original equation is
Now Let we form the new equation:
Equation 2 is kept unchanged:
Equation (2):
Equation 1 is replaced with the sum of equation 1 and a multiple of equation 2:
Equation (1): 
Now solve this two equations: 
Multiply (1) by 7 and (2) by 8,
Subtracting,
implies
Then x=2.
so the solution for the new system of equation is x=2, y=1.
This Show that the solution to the system of equations 8x − 5y = 11 and 7x − 8y = 6 is the same as the solution to the given system of equations
Width: W
Length: L = W + 8
Perimeter = 2W + 2L = 2(W) + 2(W+8) = 184 (ft)
Solving for W: 2W + 2W + 16 = 184 (ft)
4W = 168 ft, and so W = 42 ft.
The length, L, is (42 + 8) ft = 50 ft. (answer)
