A ghost on a 135 feet cliff perpendicular (at 90 degrees) to the ground looks down at an angle of 16 degrees and sees a
Bogdan [553]

To solve this problem you must apply the proccedure shown below:

1. You can make the diagram attached, where the ghost is identified as G and the the werewolf as W. The distance between both of them is <em>y</em> and the distance of the werewolf from the base of the cliff is <em>x</em>.

2. Let's calculate <em>y</em>:

Cos(16)=\frac{135}{y}

y=\frac{135}{Cos(16)}

y=140.44 ft

3. Now, let's calculate <em>x</em>:

Tan(16)=\frac{x}{135}

x=(135)(Tan(16))

x=38.71 ft

The answer are:

  • The ghost is 140.44 feet from the werewolf.
  • The werewolf is 38.71 feet from the base of the cliff.

8x - 5 = -29 <br><br> Find x
Masja [62]

If you want to find x first, you would have to do:

8x-5=-29

8x-5+5=-29+5

I added 5 to both sides so i can leave 8x by itself. Now by simplifying:

8x=-24

8x/8=-24/8

I divided both sides by 8 so I can leave x by itself to get the answer:

x=-3

what is the volume of a cylinder, in cubic with a height of 2 inches and a base diameter of 18 inches Round to the nearest place
dem82 [27]

Answer:

V = 508.938 in^{3}

Step-by-step explanation:

The equation to find the volume of a cylinder is:

V = \pi r^{2} h

r = radius

h = height

In the question it gives us the height (2 inches) and the diameter (18 inches).

We need to find the radius from the diameter. To do this, divide the diameter by 2:

r = 18/2 = 9

Now, plug everything into the equation and solve:

V = \pi (9)^{2} (2)

Use a calculator to get the answer:

V = 508.938 in^{3}

(Side note: I don't know what place to round to because in the question it says to "round to the nearest place" but doesn't say tenth, hundred, etc. If the question on your homework says tenth then the answer would be 508.9, hundredth = 508.94, thousandth = 508.938)

Hope this helps!! If you have questions please comment them under this!
