We know that the escape velocity of Earth is about 11.2Km/s but what if we give that same velocity to an object at any angle let's just take 30° will it still escape from Earth's gravitational field or not

Escape velocity is not dependent on direction. It was initially calculated using conservation of energy (setting kinetic energy equal to potential energy).
Since energy is a scalar quantity, the angle $\theta$ that an object is launched at will not change the escape velocity.
So $v_{escape} = 11.2 $ km/s
