HELP ASAP a ramp is built so that the highest point is 5feet above the ground the base of the ramp is 12 feet horizontally. what is the length of the rampa.7b.13c.17d.19**feet**

Answer 1

Draw a diagram of the situation:

Notice that a right triangle is formed with the ramp, the horizontal side and the vertical side.

Use the Pythagorean Theorem to find the length L:

`\begin{gathered} L=\sqrt[]{(12)^2+(5)^2} \\ =\sqrt[]{144+25} \\ =\sqrt[]{169} \\ =13 \end{gathered}`

Therefore, the length of the ramp is 13 feet.
