Best ResponseYou've already chosen the best response.2if you are able to prove that QM and QN are congruent, and RP and RO are congruent, then you would be able to prove that the figure is trapezoid \[QR=\frac{ 1 }{ 2 }(MP+NO)\]

Best ResponseYou've already chosen the best response.2what should we do to get the value of x? I provided the equation for the medial of trapezoid for you to use to find the value of x. I prefer that you participate in solving and not be a spectator.

Best ResponseYou've already chosen the best response.2QR = 1/2(MP+NO) x+15 = 1/2 [(9x 42) + 30] // perform the operation in the parentheses x+15 = 1/2 (9x 12) //to make our problem easier by multiply both sides by 2. this will cancel out 1/2 and 2 and will give us: 2 (x+15) = 9x  12 // distributive property on left hand side (LHS) of the equation 2x + 30 = 9x  12 // isolate terms, our x, into the LHS by subtracting 9x on both sides of the equation. this will give us 2x 9x + 30 = 9x  9x 12 // perform the operation. 7x + 30 = 12 // continue to isolate our x by subtracting 30 on both sides of the equation. this will give us: 7x + 30  30 = 12  30 // perform the operation 7x = 42 // look for the value of x by dividing both sides of the equation by 7 x = 6
