Total Unit of Triangle = 2+4+9 = 15
Value of one unit = 180/15 = 12
So, Angles = 2(12) : 4(12) : 9(12) = 24 : 48 : 108
In short, Your Angles would be: 24, 48 & 108
Hope this helps!

Answer:
about 3.21 hours each
Step-by-step explanation:
First divide 330 by 6 since there are six people.
Every person needs to do 55 decorations.
I would take the average of 2-4 minutes and multiply it by 55.
55 x 3.5 = 192.5 minutes
to convert to hours divide by 60.
192.5 / 60 = 3.21
Answer:
$8825.10
Step-by-step explanation:
Interest total= P x r x t
P = principal amount, or $6900
r= interest rate, or 0.031
t = time, or 9 years
6900 x 0.031 x 9 = 1925.10
You now add this to the original amount
6900 + 1925.10 = $8825.10
