A swimmer wants to cross a river from point $A$ to point $B$ . Line AB makes an angle of $30 °$ with the flow of the river. The magnitude of the velocity of the swimmer is the same as that of the river. The angle $θ$ with the line $A B$ should be _______ $°$ , so that the swimmer reaches point $B$ .

Question
