Draw the following triangles and construct circumcircles for them. In Delta XYZ, XY = 4.8 cm , angle X = 60^@ " and " angle Y =70&@

Construct a circumcircle of the triangle ABC where AB = 5cm, angleB = 75^@ and BC = 7cm

In a triangle PQR with right angle at Q , the value of ∠P is x , PQ = 7 cm and QR 24 cm , then find sin x and cos x

ABC is a triangle and PQ is a straight line meeting AB in P and AC in Q. If AP = 1 cm, BP = 3cm, AQ = 1.5 cm and CQ = 4.5 cm, prove that area of Delta APQ = (1)/(16) ( area of Delta ABC ).
