Question 1135916:  Given: KLMN is a trapezoid, KL=MN,    
            m∠1=m∠2,   LM/KN = 8/9 , Perimeter KLMN=132 
Find: The length of the midsegment

There is not enough information given.
  
The statement that m∠1=m∠2 is useless, since angles 1 and 2 are not defined.
  
So all we have is an isosceles trapezoid with bases of length 8x and 9x and two sides of length y, with a perimeter of 132:
  
 
  
One equation, two unknowns, with the only restriction being that x and y are non-negative, means an infinite number of solutions.
  
We know the length of the midsegment is 17x/2, but that value is dependent on y; we can't find a unique solution.
