Which line segment is a diameter of circle F?
FE¯¯¯¯¯
AC¯¯¯¯¯
EC¯¯¯¯¯
BA¯¯¯¯¯

The answer is AC because that line segment passes through the middle of the circle and has endpoints on the circle

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
