The statement is contradictory, because it is said that every member of the family gives a gift to every other member of the family. And from 10 members, there are just 2 exchanging. Anyway, maybe they are only 2 members exchanging the gifts at that point in time.
So, each member will exchange 9 gifts (that is 10 members total minus herself), and 2 members are exchanging gifts at that point, so 18 gifts are being exchanged.

It’s c i know bc i had the question
Answer:
angle a = 20 degrees
angle b = 160 degrees
angle c = 15 degrees
angle d = 75 degrees
Step-by-step explanation:
Every straight angle equals 180 degrees, and every right angle is half of that (90 degrees). This is helpful to remember during geometry- every unknown angle is part of either a right or a straight angle. Honestly, if you look carefully enough, most of the answers are supplied in opposite angles.
Hope this helps! If not, let me know! :)
