This is GMAT question is from GMAT Official Guide 2019 Quantitative Review and the figure and word problem is in the image if you can't see it, then can someone make the picture look nice( I know someone on this forum knows how to do that somehow??). The answer is C
I used A squared + B squared = C squared
I did RS squared + ST squared = RT squared. That means 4 squared + 5 squared = 41. That means RT equals Square root of 41. Then you do RT squared plus QR squared = QT squared. 41 + 4 = 45 squared. QT = square root 45. Then you use PQ now and with QT you can find PT.
3 squared = 9. 9 plus PT squared = QT squared. Pt squared equals 36 and PT equals 6. PT equals 6, so how can I answer this question??
