Answer:
ACD = 120°
Step-by-step explanation:
Exterior angle theorem.
3x = (x + 12) + (x + 28)
3x = 2x + 40
x = 40
ACD = 3x = 3(40) = 120°
A 3rd degree polynomial of any sort times a 4th degree polynomial of any sort will result in a 7th degree polynomial.

The correct answer is 700 months .

What is simple interest?</h3>
- Simple interest is based on the principal amount of a loan or the first deposit in a savings account.
- Simple interest doesn't compound, which means a creditor will only pay interest on the principal amount and a borrower would never have to pay more interest on the previously accumulated interest.
Given,
I = 105
P = 100
r = 0.15
Now use simple interest formula,

105=100×(0.15)×(t)
Swap sides so t is on the left.
100 ×(0.15)×(t)=105
Divide both sides by 100.
0.15t=1.05
Divide both sides by 0.15
t=700
So, we see that it takes 700 months to earn this amount.
