  • It would be better if you showed your work too, including where and why you’re stuck.

  • Thank you for replying and sorry for not providing enough information. I simply don't get the question, when it says to work out the ratio of PX : XQ, I just don't get what I am supposed to do. I know what a ratio is but I am confused over what to do. Thank you for understanding

  • You need to use the Pythagorean Theorem to calculate the length of the sides $overline{PX}$ and $overline{XQ}$. Then, you can find the ratio of their sides by $frac{overline{PX}}{overline{XQ}}$.

  • So the ratio will simply be: "The length of PX : The length of XQ"?

Note that $triangle PXR, triangle QXR$ are right angled at $X$. Use the pythagorean theorem in both triangles:



$PX^2+RX^2=PX^2+16^2=PR^2=20^2implies PX=sqrt{20^2-16^2}$



$QX^2+RX^2=QX^2+16^2=QR^2=34^2implies QX=sqrt{34^2-16^2}$



Can you now work out the ratio $PX:QX=frac{PX}{QX}$ in simplest terms?

  • The ratio would be 12:30 = 6:15 = 2:3
    – THELichCA
    Dec 7 at 8:19










  • Yes, that's correct. $12:30::2:5$
    – Shubham Johri
    Dec 7 at 8:20










  • You simplified the ratio incorrectly. $6:15 implies 2:5$. Other than that, it’s correct.
