Best ResponseYou've already chosen the best response.0The two adjacent line are a tangent tot eh circle and also thery along with the lines forming the 70 angle form a quadrilateral. The sum of angles in a quadrilateral is 360 and angle formed by tangent is 90. Now I guess you can solve

Best ResponseYou've already chosen the best response.0My point is that when ever you solve a question solve it frm the basic theorems that are present and not the derived ones
