A circle is inscribed in a quadrilateral ABCD touching sides AB, BC, CD and DA at the points P, Q, R and S respectively. If BP = 5 cm, SD = 7 cm and BC = 8 cm, then the length of DC is?
Answer & explanation
Correct answer: option 2
Tangents of a circle from same point is equal
BP = BQ = 5
CQ = CR = 3
SD = RD = 7
DC = DR + RC = 7 + 3 = 10 cm
