A bike ramp is built in the shape of a right triangle. The base beam has a length of 18.2 m, and the ramp has a height of 11.65 m. What is the length of the ramp surface to the nearest tenth of a meter?

Answer 1

To find the length of the ramp surface, we can use the Pythagorean theorem, which states that the square of the hypotenuse (in this case, the length of the ramp surface) is equal to the sum of the squares of the other two sides (the base beam and the height).

So, the length of the ramp surface can be calculated as:
length of ramp surface = sqrt((base beam)^2 + (height)^2)
length of ramp surface = sqrt((18.2)^2 + (11.65)^2)
length of ramp surface = sqrt(331.24 + 135.72)
length of ramp surface = sqrt(466.96)
length of ramp surface ≈ 21.6 m

Therefore, the length of the ramp surface is approximately 21.6 meters.
