Tanesha needs to measure the height of a flagpole. She is 5'9" tall. She finds that if she stands 12 ft from the base of a flagpole, the top of her head touches the guy wire holding the flagpole up. The guy wire is anchored 15 ft from the base of the pole. How tall is the pole?

ok i’m in grade 10 and have this assigned for homework and i just want people to know I WILL NEVER EVER NEED TO KNOW THIS IN REAL DAILY LIFE. IF SHE WANTS TO KNOW THE STUPID HEIGHT OF THE FLAGPOLE THEN MESSURE IT LIKE A NORMAL HUMAN BEING THIS IS STUPID

As always, draw a diagram.

She is standing 3 ft from where the wire is attached to the ground. Using similar triangles (in inches), the height h can be found by

69/36 = h/180

To find the height of the pole, we can use similar triangles. Let's label the height of the pole as "h".

1. Start by drawing a diagram to visualize the problem.

Let the base of the pole be point A, the top of Tanesha's head be point B, and the point where the guy wire is anchored be point C.

A ------------------ B
|\

| \
C -------

2. From the given information, we know that points B, A, and C form a right triangle and that points A, B, and C form similar triangles.

3. Using the concept of similar triangles, we can set up the following proportion:

(height of pole)/(distance from Tanesha to the pole) = (height of Tanesha)/(distance from Tanesha to the guy wire)

h/12 = 5'9"/15

4. Convert the height of Tanesha from feet and inches to only inches. Since there are 12 inches in a foot, 5 feet 9 inches is equivalent to 69 inches.

h/12 = 69/15

5. Cross-multiply the proportion:

15h = 828

6. Solve for h by dividing both sides of the equation by 15:

h = 828/15

7. Calculate the height of the pole:

h ≈ 55.2 feet

Therefore, the height of the pole is approximately 55.2 feet.

To solve this problem, we can use similar triangles. Let's consider two similar triangles: one formed by Tanesha, her height, and the distance between her and the flagpole, and the other formed by the flagpole, its height, and the distance between the flagpole and the guy wire.

Let's find the height of the flagpole:

1. First, let's convert Tanesha's height to inches, as it is a common unit of measurement. Tanesha's height is 5'9", which is equivalent to (5 * 12) + 9 = 69 inches.

2. Using similar triangles, we can set up the following proportion:

(Height of the flagpole) / (Height of Tanesha) = (Distance between flagpole and guy wire) / (Distance between Tanesha and flagpole)

Let's substitute the known values into the proportion:

(Height of the flagpole) / 69 inches = 15 ft / 12 ft

(Height of the flagpole) / 69 inches = 5 / 4

Now, let's solve for the height of the flagpole:

(Height of the flagpole) = (69 inches * 5) / 4

(Height of the flagpole) = 345 inches / 4

(Height of the flagpole) = 86.25 inches

Therefore, the height of the flagpole is 86.25 inches.
