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]
