Question

In the diagram, VW = 3, WX = 4, and VX = 8. Is line WX tangent to point V?

Answer 1

No. If line WX would have been a tangent, the angle VWX should have been 90 degrees. If it would have been 90 degrees, using the pythagoras theorem, side VX should have been 5. But it's not 5, neither angle VWX is 90 degrees nor is the line WX a tangent to the circle
