Yeah, i’ve tried to do this problem and still have no clue can anyone me out maybe? and maybe explain how you got your answer too, so i can get it

Your answer is 70.

As this is a parallelogram, lines PN and MO are the same length. This also means K is the midpoint of line PN. From this, you can deduce that PK = KN as both are half of line PN

So, equating the expressions gives

And now we have to rearrange and solve for x by factorising

Now, if we substitute both values into PK =5x, we know that x cannot be - 2, as we cannot have a negative length.

Using x = 7 and substituting

Then multiplying by 2 to give the entire length of PN
