1. Problem Description

The problem asks to find the angles among 420420^{\circ}, 790790^{\circ}, 11301130^{\circ}, 70-70^{\circ}, 560-560^{\circ}, and 1010-1010^{\circ} that have the same terminal side as 7070^{\circ}.

2. Solution Steps

Two angles have the same terminal side if their difference is a multiple of 360360^{\circ}.
We check each angle:
* 42070=350420^{\circ} - 70^{\circ} = 350^{\circ}. This is not a multiple of 360360^{\circ}.
* 79070=720=2360790^{\circ} - 70^{\circ} = 720^{\circ} = 2 \cdot 360^{\circ}. This is a multiple of 360360^{\circ}.
* 113070=10601130^{\circ} - 70^{\circ} = 1060^{\circ}. Dividing 10601060 by 360360 gives approximately 2.942.94, so it is not a multiple of 360360^{\circ}.
* 7070=140-70^{\circ} - 70^{\circ} = -140^{\circ}. This is not a multiple of 360360^{\circ}.
* 56070=630-560^{\circ} - 70^{\circ} = -630^{\circ}. This is not a multiple of 360360^{\circ}.
* 101070=1080=3360-1010^{\circ} - 70^{\circ} = -1080^{\circ} = -3 \cdot 360^{\circ}. This is a multiple of 360360^{\circ}.
Therefore, the angles that have the same terminal side as 7070^{\circ} are 790790^{\circ} and 1010-1010^{\circ}.

3. Final Answer

790790^{\circ} and 1010-1010^{\circ}
