Answer:
The distance from the ramp's contact point with the ground and the base of the platform is 10.90 feet.
Step-by-step explanation:
As
- A ramp 12 feet long is leaning against a raised platform which is 5 feet above the ground.
And
- We have to determine the distance from the ramp's contact point with the ground and the base of the platform.
Since we are looking for the side of 'b' right triangle.
Please check the attached figure.
So using the Pythagorean formula:
Fora right angled triangle with sides a, and b the hypotenuse c is defined as
feet
Therefore, the distance from the ramp's contact point with the ground and the base of the platform is 10.90 feet.
First of all, you need to recognize that ∠GHE and ∠AHD are "vertical" angles, so they are equal.
Then, you need to recognize that ∠AHD and ∠AHK are complementary angles.
Then you have
.. ∠AHD +∠AHK = 90
.. ∠GHE +∠AHK = 90
.. (60 -x) +(2x -6) = 90
Now, you have a linear equation in x that is easily solved.
.. x +54 = 90 . . . . . collect terms
.. x = 36 . . . . . . . . . subtract 54 . . . . . . . . . matches selection B*
___
* except that the answer is actually 36, not 36°. The variable x is used in an expression to which the units "degrees" are attached. x is a pure number; x° is 36°.
