Hi, first, the grammar has been a bit confusing, but i think i have it. the question is that one group has 28 baseball cards and another has 68, right? in order to tell how much each person could have received, we first have to know how many people there were and divide the numbers of cards by that. since you never specified the number of people in the groups, i can't solve it completely. all together you have 96 cards. i hope this helps.
Angles of a triangle = 180 degrees T + C = 110 degrees, and T=C (according to the definition of an isosceles triangle). measure of T is 110/2 which equals 55 degrees
