Question

Triangles QPT and QRS are similar. Find x.

Answer 1

since QPT and QRS are similar,therefore,\[\frac{QP}{QR}=\frac{PT}{RS}=\frac{QT}{QS}\]
now you can get x by substituting values.

Answer 2

10/10?

Answer 3

I'll show you the way I do it.

Answer 4

8/12=x/20

Answer 5

cross multiply

Answer 6

x=160/12

Answer 7

so now we have to write it according to the corresponding sides so
\[ \frac{x}{20}= \frac{8}{12}\]
\[x= \frac{8}{12} \times 20\]
x = 13.333333
