A ramp 12 feet long is leaning against a raised platform which is 5 feet above the ground. What is the distance from the ramp's contact point with the ground and the base of the platform?

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

And

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.

i think it is 18

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
