A ramp 17 1/2 feet in length rises to a loading platform that is 3 1/2 feet off the ground. Find the angle that the ramp makes with the ground.

Answers

Answer:

The angle that the ramp makes with the ground is 11.54°

Step-by-step explanation:

From the image attached, we can see that the length of 17 1/2 ft corresponds to the hypotenuse in a right triangle, the length of 3 1/2 ft corresponds to the opposite side.

We can use the fact that the sin(θ) = (Opposite)/(Hypotenuse) to find the angle that the ramp makes with the ground.

sin(\theta)=(3.5)/(17.5)

The angle is equal to

\theta = sin^(-1)((3.5)/(17.5) )\n\theta = 11.54\°

Final answer:

The angle that the ramp makes with the ground can be found using the concept of tangent in trigonometry. By dividing the height of the loading platform by the length of the ramp and taking the inverse tangent of the result, we find the angle to be approximately 11.3 degrees.

Explanation:

This question can be solved by using trigonometric principles, specifically the tangent of an angle in a right triangle. The tangent of an angle θ (theta) can be defined as the ratio of the side opposite the angle to the side adjacent to it.

In this scenario, the ramp forms a right triangle with the ground and the vertical line from the loading platform to the ground directly below it. The height of the platform, or the 'opposite' side, is 3 1/2 feet, and the ramp, or the 'adjacent' side, is 17 1/2 feet.

Therefore, we can say that: tan θ = (3.5 / 17.5)

To find the value of θ, we take the inverse tangent (or arc tangent) of the quotient. Using a calculator to do this (remember to set your calculator to degree mode), we find θ to be approximately 11.3 degrees.

Thus, the angle that the ramp makes with the ground is about 11.3 degrees.

Answer:

x = 56°

Step-by-step explanation:

Base angles of an isosceles triangle are equal.

This:

The angle of the triangle to our right, which is the third unequal angle = 180 - 2(31)

= 180 - 62

= 118°

The base angle of the triangle to our left = 180 - 118 (angles on a straight line)

= 62°

x = 180 - 2(62)

x = 180 - 124

x = 56°

miguels physical eduction class lasts for 3/4 of an hour. today they spent 3/4 of that time playing dodge ball. what fraction of an hour did he spend playing dodge ball?

Answers

the answer is 9/16

there are two ways you can get this
take 3/4 times 3/4 to get 9/16
or
3/4 of an hour = 45 min and 3/4 of 45 min = 33.75 min and 33.75/60(minutes in an hour) = 9/16
3/4 of 60 minutes is 45 minutes. Then if they played dodge ball 3/4 (75%) of that time the answer is: 3/4 (75%) of 45 minutes = 33.75 minutes. Then 33.75 minutes divided by 60 minutes = 0.5625 (56.25%) of 60 minutes playing dodge ball. Liv219 has already given you the answer in fraction form.
