The image is a bit hard to make out, so I'm going to make some guesses. It looks like it says PN=12, QP=8, and PM=17, and you're asked to find QR.

You know that \Delta NPM and \Delta NQR are similar, which means their corresponding sides are proportional in length. So there's some constant c such that

NP=cNQ
PM=cQR
MN=cRN

To find QR, you need to know PM and the constant c.

Clearly, NQ=NP+PQ=12+8=20. So, the first equation becomes

NP=cNQ\iff12=20c\implies c=\dfrac{12}{20}=\dfrac35

Then in the second equation, you have

17=\dfrac35QR\implies QR=17\times\dfrac53=\dfrac{85}3=28.\overline3

The base of a pyramid has n sides.<br> Write an EXPRESSION for the number of faces of the pyramid.
ser-zykov [4K]
<span>In general, if the pyramid has 'x' sides, then it will have 'x' lateral faces. Total Number of Faces = Number of Base Faces + Number of Lateral Faces. Total Number of Faces = 2 + x. So the formula is F=x%2B2 where "x" is the number of sides that the pyramid has and "F" is the total number of faces.</span>
