Question

In Triangle QRS, X is the midpoint of QR, Y is the midpoint of RS, and Z is the midpoint of QS.

Answer 1

Answer:

Step-by-step explanation:

I just answered this for someone else... here is the same answer I gave them

QR + RS +SQ = perimeter

2(XR) + 2(YS) + QS = perimeter ( b/c multiplication is communicative  SQ=QS)

2*5 +  2 * 7 + 20 = perimeter

10 + 14 + 20 = p

44 = p
