Answer:
A=75
B=60
C=45
Step-by-step explanation:
5+4+3=12
every triangle is equal to 180 so we divide
180/12=15
then we multiply each angle by 15
5*15
4*15
and 3*15
don't forget to check your work by adding the answers together to get 180
<span>14+ 9 + 2+ 13+ 16+3+ 13+ 10 = 80
80/8 = 10
answer
mean = 10

Just multiply the order pairs by 3. For example,
(2,0) times 3 = (6,0)
(3, -1) times 3 = (9,-3)
(-2,-5) times 3 = (-6, -15)
The other person is correct the answer is C
