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? |
8 10 11 13 |
10 |
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 |
