Hi,

11km/s.

Escape speed of a body from Earth's surface is given by: vmin = 2gR. This expression is obtained by conservation of energy and doesn't involve in which direction the body is thrown/projected. So, irrespective of the angle of projection, escape speed of the body from Earth's surface remains constant i.e. ≈11 km/s
