What do you think the answer is? Tell me and I will help you some more! :)
Step 1
<u>Find the value of TS</u>
we know that
if PQ is parallel to RS. then triangles TRS and TPQ are similar
so

solve for TS

we have


substitute

Step 2
<u>Find the value of SQ</u>
we know that

we have


substitute

therefore
<u>the answer is</u>
the value of SQ is 
Step-by-step explanation:
This is right m does equal 13. D first you multiply everything in the para thesis and so on
