In PQR,QM perp PR and PR^(2)-PQ^(2)=QR^(2). Prove that QM^(2)=PM xx MR

In ∆PQR , if PQ = QR and ∠Q = 100° , then ∠R is equal to

If P:Q:R=2:3:4 and P^(2)+Q^(2)+R^(2)=11600 , then find (P+Q-R)

In a triangle PQR, right angled at Q. PQ=5 cm, QR=12 cm. Find the length of QM , if M is the mid point of PR .

In a angle PQR , M lies on PR and between P and R such that QR=QM=PM . If angle MQR=40^@ , then find angle P .

In Delta PQR/_R=/_P and QR=4cm and PR=5cm Then the length of PQ is

If every pair from among the equations x^ 2 + p x + q r = 0, x^2+px+qr=0, x^2 + q x + r p = 0, x^2+qx+rp=0 and x^2 + r x + p q = 0, x^2+rx+pq=0 has a common root then the product of three common root is (A) pqr (B) 2pqr (C) (p^2q^2r^2) (D)none of these
