P, q, and r are three different points. pq = 3x + 2, qr = x, rp = x + 2, and . list the angles of pqr in order from largest to smallest and justify your response.

PQR is a triangle
QR = x  ⇒ x>0
If x>0 then:
QR is the smallest side
PQ is the largest side

In the triangle, the largest angle lies opposite the largest side.
The angles of ΔPQR in order from largest to smallest:
∠R is largest    [opposite to PQ]
∠Q is middle    [opposite to RP]
∠P is smallest   [opposite to QR]
