Question

Pls help due tomorrow

Your keys drop from the top of the tower and fall straight to the ground. You want to know how far from the base of the tower the keys landed. Draw a right triangle that will help you solve the problem. label each triangle with the information you know. (the tower is 150 meters tall with a 72-degree angle )

2. using the known angle, what side is known? What side is unknown? Use opposite, adjacent, or hypotenuse in your answer.
known side ___
unknown side ___

3. What trigonometric ratio would you use to find the distance from the base of the tower to your keys? identify your choice, and then calculate the distance.
Trigonometric ratio (name) ___
Calculation (Show your work): ___

4. While you're at the top of the tower, you see an ant walking along the edge of the building. if the ant were to walk straight down the side of the tower until it reached the ground, how far would the ant travel? Which trigonometric ratio would you use to find this distance? use the ratio to find the measurement.

5. confirm that your answer to question 5 is correct using the Pythagorean theorem instead of trigonometric ratios.

6. The leaning tower of Niles, in Illinois, is a replica of the famous Leaning tower of Pisa. it was completed in 1934. the tower of Niles is 94 feet high and makes an angle of 85.5 degrees from the ground to the top of the tower. if you drop your keys from the top of this tower, how far from the base of the tower would they land? ​

Answer 1

know side: 3

Unknown side: 5

Answer: The trigonometric ratio that I would use to find the distance from the base of the tower to the keys is the tangent; tan (86°) = height / distance.

Explanation and calculation:

You can draw a right triangle with angle 86°, opposite leg equal to the height (50 meter) and adjacent leg equal to the distance from the base of the tower to the keys: tan (86°) = 50 m / x

=> x = 50 m / tan(86°)

x = 50 m / 14.30 = 0.98 m

Answer: 0.98 m
