<u>Given</u>:
Given that the measure of arc DF is 162°
We need to determine the measure of ∠E
<u>Measure of ∠E:</u>
The measure of ∠E can be determined using the inscribed angle theorem.
Thus, by inscribed angle theorem, we have;
Substituting , we get;
Dividing, we get;
Thus, the measure of ∠E is 81°

Step-by-step explanation:
The formula for compound interest, including principal sum is:
, where:
- A is the future value of the investment/loan, including interest
- P is the principal investment amount
- r is the annual interest rate (decimal)
- n is the number of times that interest is compounded per unit t
- t is the time the money is invested or borrowed for
∵ Phineas puts $800 into a certificate of deposit
∴ P = 800
∵ The rate of deposit is 3.39%
∴ r = 3.39% = 3.39 ÷ 100 = 0.0339
∵ The money is compounded monthly
∴ n = 12
∵ t = 3
- Substitute these values in the formula above
∴
∴
∴ A = 885.51407
- Round it to the nearest cent ⇒ hundredths place
∴ A = 885.51
