Section AWhich type of solution will the pair of linear equations+ 3y 4 and 2 ty- 5 have?1.2. In the given figure, AB, AC and AD are tangents. If AB = 5cm,find AD. |

Answer» 1) no solution is there as a1/a2 is not equal to b1/b2 not equal to c1/c2 As AB,AC are tangents to one circlethey are equal ( th.tangents from an external point to a circle are equal)AB=AC=5------------------1 AC and AD are tangents to another circle.they are equal too(th.tangents from an external point to a circle are equal)AC=AD----------------------2from 1 AND 2,AB=AC=AD=5thus length of AD=5 |
