5% of 500 dollars is 25 dollars, so since 5% is 25 dollars, multiply that by how many years he can have it (18). So 18 * 25 = 450. 450 added to the starting 500 dollars is 950 dollars. Your welcome, I'm new so glad I could help.

A 14 ft ladder is used to scale a 13 ft wall. At what angle of elevation must the laxder be situated in order to reach the top o

Crazy boy [7]

Answer:

The angle of elevation is equal to 68.2 degrees

Step-by-step explanation:

As you can see from the image below we are trying to find the angle on the bottom right.

We know that the hypotenuse is equal to 14 and we know that the opposite is equal to 14. This means that we will be using Sine.

sin x = 13/14

divide:

sin x = 0.9285714286

now we need to use sin^-1

sin^-1 (0.9285714286) = 68.21321071

Round 68.21321071 to the nearest tenth:

68.2

The angle of elevation is 68.2 degrees!
