Answer:
6 cm,12 cm,8 cm
Step-by-step explanation:
add the perimeter of the first triangle to get 65
then divide 65 by 26 to get 2.5
then divide all the side lengths by 2.5
15/2.5=6
20/2.5=8
30/2.5=12
Y=15-0.04x since the value at x=0 is still 15, then it starts from 15, and it goes down 0.4 after 10=x so 0.4/10
