Help with this problem
Ne4ueva [31]

Answer:


Step-by-step explanation:

The measure of angle one is 115 degrees because the angle with 115 degrees and angle one are alternate interior angles and alternate interior angles are congruent.

The measure of angle two is also 115 degrees because angle one and angle two are vertical angles and vertical angles are congruent.

The measure of angle three is 148 degrees because same side interior angles are always supplementary (supplementary = adds up to 180 degrees).

The measure of angle four is also 148 degrees because angle three and angle four are vertical angles and vertical angles are congruent.

The measure of angle five is 32 degrees because angle five and the angle which is given to be 32 degrees are alternate interior angles and alternate interior angles are congruent.

The measure of angle six is 65 degrees because straight lines are 180 degrees on each side. Angle six and the 115 degree angle (which is given) are supplementary (adds up to 180 degrees) because definition of a straight line.

Lamont retired at age 55 and rolls over $300500
Arlecino [84]

If Lamont withdraws $2,750 monthly, he will be <u>66 years old</u> (after 134.326 months) when the money runs out.

<h3>How is the number of monthly withdrawals calculated?</h3>

We can calculate the number of monthly withdrawals using an online finance calculator.

It determines the number of periods it will take for the investment to be exhausted, given an interest rate of 3.8%.

I/Y (Interest per year) = 3.8%

PV (Present Value) = $300,500

PMT (Periodic Payment) = $-2750

FV (Future Value) = $0

<u>Results</u>:

N = 134.326 months

Years = 11 years (134.326/12)

Age at FV = $0 is 66 years (55 + 11)

Sum of all periodic payments = $-369,397.09 (134.326 x $-2,750)

Total Interest = $68,897.09

Thus, making a monthly withdrawal of $2,750 will exhaust the investment when Lamont turns <u>66</u>.
