Pythagorean identities:
sin2(0)+ cos?(0) = 1
Which statement(s) are true based on the
Pythagorean identities?
sin? 6 -1+cos?
tan2 (8) +1= sec (0)
1+cot?(0) = csc (0)
1 = sec? 6-tan?
cote-csc20-1
1-tan? --sec?
- cos? 6 = sin? 0-1

1. There are 648 total combinations that can be chosen.

2. After she choses two possiblilities the total number changes to 108 total posibilities to chose from

Step-by-step explanation:

possibility: 1/2 x 1/3 x 1/2 x 1/6 x 1/9 = 648

then you remove the first two because she chose those ones

1/2 x 1/6 x 1/9 = 108 possibilities left
