Question

What is the top of the flag pole above ground in inches?

Answer 1

Answer:

13ft 10.2in

Step-by-step explanation:

First let's convert 3ft to in.

3 * 12 = 36 in

Now let's find the angle

We use tangent because we know the opposite and adjacent distances.

tan x = 36/13

tan x = 2.7692

On your calculator, input the value of your tangent. Then press "inv." This should give you the angle associated with that value. The angle associated with tan 2.7692 is 70.14 degrees.

Now that we know the angle we can find the height.

We use tangent again.

tan 70.14 = x / 5     We don't know the opposite but we know the adjacent length is 5ft.

2.77 * 5 = x

13.85 ft = x

To get it in ft and inches multiply .85 by 12

.85 * 12 = 10.2

13ft 10.2in
