I´m currently pulling a C in math. I won´t get into an advanced class next year and I will be grounded for the summer if the day ends and my math grade isn´t up. It´s the last day of school.

What is the question saying exactly? I figured out the distance from one of the point to the point in the center but I don't completely understand the question.

The angle between the tangent lines and the line from the point where the tangent line touches the sphere to the center is 90 degrees because of the following property of tangent lines: |dw:1433463800706:dw|

Sum of all angles in a quadrilateral is 360 degrees. We know two angles are 90 degrees, because they come from tangents and one is given as 138 degrees. So the angle of the arc between the two tangent points is the same as the remaining angle: 360 - 90 - 90 - 138. |dw:1433463982564:dw| The measure of the arc is also 42 degrees. Does this make sense?
