HarlanHill Posted May 26 Report Share Posted May 26 Hi friends! I got the following assignment in college. In parallelogram PQSR, what is PQ? (2x + 5) cm a) 2 cm b) 5 cm c) 6 cm d) 9 cm I will be very grateful for your help in solving it. Quote Link to comment Share on other sites More sharing options...
JeffreysTubes8 Posted May 27 Report Share Posted May 27 Hi Harlan 👋  this problem takes me back to basics. One of the most simple problems was to get rise over run of -5/2 and when you have PQ in that sort of parallelogram with sums 2.5 obvs it’s 5 or b) Quote Link to comment Share on other sites More sharing options...

Your answer is silly. Quote Link to comment Share on other sites More sharing options...

You have only given us the fact that PQ = (2x + 5) cm That is not enough information to solve the problem. You must also give the value of RS. We know that opposite sides of a parallelogram are equal in magnitude. So, PQ = RS and PR = QS A typical problem statement might be PQ = (2x + 5) cm and RS = (4x + 1) solve for PQ Then, since PQ = RS The solution is very simple: 2X + 5 = 4x + 1 Then, 5 = 2x + 1 and 2X = 4 x = 2, so 2x + 5 = 9 cm side PQ = 9 cm Ans. It is a very simple problem when you provide all of the information! Â Quote Link to comment Share on other sites More sharing options...
