Answer: 16.91°

Step-by-step explanation:

1. You can draw a right triangle as you can see in the figure attached.

2. Then you can calculate the angle of elevation (α) as following:

$\alpha=arcsin(\frac{opposite}{hypotenuse})$

Where:

$opposite=32\\hypotenuse=110$

3. Now you must substitute these values. Then, the angle of elevation is:

$\alpha=arcsin(\frac{32}{110})$

$\alpha=16.91\°$

Answer:

$4127

Step-by-step explanation:

The amortization formula is good for finding this value.

A = P(r/12)/(1 -(1 +r/12)^(-12t))

where P is the amount invested at rate r for t years.

A = $600,000(0.055/12)/(1 -(1 +0.055/12)^(-12·20)) = $4127.32

You will be able to withdraw $4127 monthly for 20 years.
