What else would need to be congruent to show that abc = xyz by sas

The answer would be B. You know B and Y are equal and AB and XY are equal, so you just need the last side included in the angle.

9/12 is the answer because 3/4 times 3 each is 9/12

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)
