Geometry help please? Will give medal
Li went for a mountain-bike ride in a relatively flat wooded area. She rode for 6 km in one direction and then turned and pedaled 16 km in another. Finally she turned in the direction of her starting point and rode 8 km. When she stopped, was it possible that Li was back at her starting point? Explain.

Answer 1

6,16,8

Answer 2

consider how big the other side can be, the biggest it can be can only be 14, 8+6

Answer 3

if you keep increasing the angle between 8 and 6, you are bound to make that other line bigger and bigger
